Flora-Incognita observations enable phenological monitoring throughout Europe

/in , , /by

A new study by our research group shows that plant observations collected with identification apps can provide information about the developmental stages of plants – both on a small scale and across Europe. [Read the paper]

Why is it important to document phenology?

Many plants in temperate climates go through a cycle of flowering, leaf emergence, fruiting, leaf colouration and leaf fall every year. This process is called phenology and is strongly influenced by local climatic conditions (for example, the number of days per year on which a certain minimum temperature required for growth is reached; see “Growing Degree Day” or GDD). It is, therefore, not surprising that climate change has a substantial impact on phenology. For example, spring begins earlier than it did in the 1950s, meaning the growing season starts much earlier than it did back then. Such changes impact agricultural processes and can also lead to ecological imbalances. For example, plants begin to flower even before their pollinators are active. However, not all plants react equally to climatic changes. Species with a broader tolerance range for warm days, or where other factors determine phenology, are virtually unaffected by shifts. To gain a truly accurate understanding of the influence of climate on plant phenology, it is essential to document the phenology of as many different species as possible, in different countries and geographical regions.

How does phenological monitoring work?

Phenology is already being documented using various methods. Satellite images recognize the greening of entire areas, and cameras in treetops produce automated image series on the condition of the vegetation layer below. Such data sets allow statements to be made about large scales, but hardly allow any conclusions to be drawn about the phenology of individual species or even individuals. For this purpose, there are initiatives that are carried out with the help of trained volunteers. However, the number of these citizen scientists is constantly decreasing, and this type of data collection is usually limited to certain plant species (often trees), countries, or even smaller regions.

Is it possible to document phenology with Flora Incognita?

Data collected via plant identification apps such as Flora Incognita can be a solution. The scientists in our project already proved this in 2023: Plants are primarily noticed and photographed when they are conspicuous and also flower, bear colorful fruit, or autumn leaves. This results in observation patterns that indicate phenological events. These patterns often coincide with those published by the German Weather Service (DWD) concerning the onset of flowering species in Germany. Assuming that the DWD registers an earlier start of flowering of the elderberry in one year than in the previous year, this shift is also reflected in the identification requests from Flora Incognita.
Details of this study can be found in this article: Phenology monitoring with Flora Incognita plant observations.

A new study shows phenologies and bioclimatic correlations across Europe

Our new publication now shows that smartphone observations even reflect known supra-regional phenological patterns, such as

  • the later flowering of many species in Northern and Eastern Europe or
  • the later flowering of many species at higher altitudes, but also
  • a Europe-wide shift in the start of flowering between years, as has already been proven for Germany.

This proves that the data generated by plant identification apps is a reliable source for the occurrence of plants at a specific time and place and is well suited for answering further research questions – even on a larger scale.

The results of the study at a glance

Plants are more likely to flower when there are more warm days
We compared the Europe-wide observation data (sources: Flora Incognita and reporting platforms such as iNaturalist) from 2020 and 2021 for 20 different plant species. We found that spring-flowering plants in particular, such as the gamander speedwell Veronica chamaedrys, flowered earlier in 2020 – up to two weeks earlier than in 2021.

An analysis of the temperature at each location showed that there were significantly more days in spring 2020 on which an average of 5°C or more was reached, meaning that the plants could absorb more heat in a shorter period of time. The effect was less pronounced for species that flower later in the year, such as the tansy Tanacetum vulgare or the common viper’s bugloss Echium vulgare.

Plants flower later if they grow at higher altitudes, further east or north.
However, patterns could be recognized not only between the years but also between different regions. It is known that the same species flowers at different times depending on the location. (-> Hopkins’ bioclimatic law) For example, if the same plant species occurs in Sweden and Spain, the Spanish plant will flower a few days or even weeks earlier than the one in the north. The exact days until flowering naturally vary depending on the plant species. This regularity can also be illustrated with Flora Incognita data:

This figure shows the median of the observation data for the three plant species already presented. Pink and orange indicate that the species flowered early in the year at the respective location, while the same species flowered later at another location (coded dark green and blue). The longitudes and latitudes are clearly differentiated, as well as the low and high mountain ranges. Details of the data and methods used can be found in the publication linked at the end of the article.

All 20 plant species analyzed could be classified into one of three main patterns, illustrated here as examples. Veronica chamaedrys shows more reddish colours in 2020 than in 2021; as already mentioned, this is due to the warmer temperatures in spring 2020. Echium vulgare shows only minor responses to different climatic conditions over the years. For Tanacetum vulgare, we found that phenology shows an inverse pattern compared to the other species: Tansy is more likely to flower in eastern, northern, and high altitudes than its siblings in western, southern, and lower-lying parts of Europe. This phenomenon has also been described in the scientific literature. Species that need many warm days to flower have adapted to cold locations by shortening their vegetation period and flowering earlier.

Summary
For the first time, the new publication shows temporal and spatial shifts in plant phenology on a Europe-wide scale using data not collected explicitly for this purpose. For the users of Flora Incognita, this means that each individual plant identification satisfies more than just their curiosity. By documenting plant occurrences at a specific time in a particular place, they create a growing and robust data source on phenology that knows no national borders, includes new species, and can answer numerous further research questions.

Thank you for your curiosity.

Adopting Flora Incognita Plant Observations for Phenology Monitoring

/in , /by

Importance of Phenology
A new paper, published by the Flora Incognita Research Group, shows that the plant observations collected via Flora Incognita can support phenological monitoring initiatives. Why is that important?
Observing plant phenology helps scientists to understand how climate change affects plants, for example. If flowering periods shift due to changing climatic conditions, this can have significant consequences for ecological relationships or the spread of species. Traditionally, the phases of phenology (e.g. bud break, leaf-out, onset of flowering, and leaf senescence) are recorded manually by trained volunteers – but their numbers are steadily declining.

Traditional Phenology Monitoring
In Germany, mainly the German Weather Service conducts the “official” plant phenology monitoring (Deutscher Wetterdienst, DWD). Here, every observer is given a specific “station,” corresponding to a dedicated spot for observing one tree, shrub or herbaceous plant. The number of these stations varies depending on the observed species. This means that some species have more stations than others. During the growing season, observers need to check on the plants they are studying at least two times each week and record the day when specific pheno phases begin.

Processing Flora Incognita data
The new paper’s lead authors Negin Katal and Michael Rzanny found a way to process Flora Incognita data in a way that they resemble DWD stations: They identified the locations of the DWD stations, and for each species, created a 5 km circle around them. Within this circle, they collected all the Flora Incognita observations for that species within a certain altitude range. At least 35 of those opportunistic records were needed to create a “Flora Incognita station”. If those could not be reached, even within an additional buffer (1 km at a time, up to 55 km), no Flora Incognita station was established at that location.

Interpolation of data
In the next step, the onset of flowering in 2020 and 2021 was calculated for each of these Flora Incognita stations, and the station data was interpolated for the whole of Germany. The resulting interpolation maps show similar results for most species as the manual documentation by the DWD.

Spatially interpolated maps based on the DWD and Flora Incognita stations for the onset of flowering of Sambucus nigra and Taraxacum officinale in 2020 and 2021. The color scale indicates the day of the year of the onset of flowering in each grid cell (from: Katal & Rzanny et al. 2023).

Take-away message
The main finding of the publication is that the onset of flowering can be inferred from our plant observations – at least for annual herbaceous species or shrubs with a conspicuous flowering phase. This means that Flora Incognita data can supplement the traditionally collected phenological surveys on a broad scale, but also for many new species. This allows us to make a valuable contribution to the documentation of phenological shifts, which is of vital importance for the documentation and understanding of climate change, among other things.

We want to thank the many users of Flora Incognita who contribute to this new source of data. It is your curiosity that enables research like this.

Press Release: New AI for Flora Incognita

/in , , , /by

“Flora Incognita”, Germany’s most popular plant identification app, has been further enhanced by a new artificial intelligence (AI) – as a result, the number of identifiable plant species has tripled: around 16,000 species can be identified worldwide. The app, available in 20 languages, now also works offline. Its range of digital educational content has been significantly expanded to include a wide range of new plant information.

Scientists from the Technical University of Ilmenau and the Max Planck Institute for Biogeochemistry in Jena have improved Flora Incognita with a new technological basis of self-learning, deep neural networks. Prof. Patrick Mäder, head of the Department of Data Intensive Systems and Visualisation and project leader of Flora Incognita at the TU Ilmenau, and the research team from Jena have made great efforts to develop innovative machine-learning training methods for these networks in the last months: “We immediately applied the new methods to the Flora Incognita app and were thus able to process millions of images of plants worldwide in our data center at the TU Ilmenau. With the right images, the new networks are able to classify many plant species with an accuracy of almost 100 per cent”.

For the new app version, user-friendliness and accessibility have also been improved. Plant finds can now be captured offline in nature, i.e. without a network connection, and automatically identified later (with internet access). Germany’s most popular plant identification app is also used by teachers at schools and universities to support education. Since school devices rarely have mobile internet, in particular this target group benefits from the new offline mode.

In addition, a new gamification element has been introduced: Users can collect badges for documenting certain plant groups. With this, they not only enjoy collecting plants themselves over a longer period of time,but they also strengthen the awareness of biodiversity in their social environment. At the same time, the app creates an incentive to document already known species or other plant groups, which provides scientists with important data for their research projects.

Another new feature is the possibility to use Flora Incognita for citizen science projects. Lay people involved in the project can identify plants as usual, for example, invasive species of a region, special trees, or the plant diversity of a school campus.  Those responsible for the citizen science project then receive the anonymized observation data for scientific and nature conservation evaluation.

But not only the technology of the Flora-Incognita app has improved. The data basis and the underlying information have also been expanded. Citizen scientists, i.e. interested laypeople, have contributed to this. With the “Flora Capture” app, which was specially developed for the scientific documentation of plants, thousands of images from defined perspectives have already been transmitted, which have contributed to a significant improvement in the identification accuracy of the German flora, especially for critical plant groups such as grasses. Students of the University of Applied Sciences Erfurt participated in the recording of thousands of trees, so that now identification is also possible in winter on the basis of bud images. The authors of the book “African Plants – A Photo Guide” and members of the Geisenheim University of Applied Sciences and the Dresden University of Applied Sciences provided further important data for the expansion of the identifiable species.

Co-project leader Dr. Jana Wäldchen from the Max Planck Institute for Biogeochemistry Jena announces that the additional information offered in the app will be further expanded in the coming months: “We plan to supplement the plant fact sheets with additional exciting details. For example, we are thinking of information on how pollinator-friendly a species is or whether it is invasive. In this way, we would like to provide our users with interesting plant knowledge after the identification.

The future of key-based plant identification – a user study

/in , /by

Our publication “Towards more effective identification keys – a study of people identifying plant species characters” shares insights into this by systematically examining how well people with different backgrounds in botany perceive, understand and relate morphological plant characteristics. In the end, our assessment suggests a set of design principles for intuitive and user-friendly identification keys.

Read it here: Towards more effective identification keys – a study of people identifying plant species characters

Context

The correct and quick identification of plant species plays an important role in the protection of biodiversity, because people can only protect what they know. Automated species identification via apps like Flora Incognita can help closing the knowledge gap, but still the most common way of identifying plant species is working with character keys in printed books. For laypersons, these keys are often difficult to understand because of the widespread use of technical terms and the lack of easily understandable illustrations.

But biodiversity monitoring often involves or even relies on citizen scientists. In many cases, detailed information on species, phenological characteristics or other markers are required to fulfill the given tasks. To be able to keep and grow the number of citizen scientists contributing to monitoring projects, new approaches to support beginners would be helpful – especially in building species identification skills based on plant characteristics quickly and reliably.

Why is the correct perception of plant characters important?

In this example, you can see pictures of the European buckthorn (Rhamnus cathartica) and the common dogwood (Cornus sanguinea). On first sight, both species look very similar, so the exact perception and description of the leaves’ edges is a determining factor of species identification:

A leaf of Cornus sanguinea, the common dogwood

Cornus sanguinea, the common dogwood

A leaf of Rhamnus cathartica, the European buckthorn

Rhamnus cathartica, the European buckthorn

With its grey-brown bark and often thorny branches, Rhamnus cathartica has elliptic to oval leaves with serrated margins.Cornus sanguinea on the other hand has dark greenish-brown branches with elliptic to oval leaves that have an entire margin.
The determining factor in this case is one adjective that needs to be known, understood and perceived to identify the plant in question.

The study

We conducted an online survey with 484 participants. After assessing the participant’s prior plant and species knowledge, they were given the task to identify morphological plant characters from a number of plant images, supported by pictograms, as shown below.  In total, 25 different plant characters were shown on 6 images from different perspectives.

Findings

On average, the participants identified 79% of the characters correctly, even those without extensive species knowledge. Those who declared themselves as intermediate or expert in terms of plant expertise needed less images of the respective plant to give a clear answer, and felt overall more sure about their answer. On average, flower-related characters were identified significantly more often and faster than leaf-related characters. Also, flower-related characters needed less images to find a definite answer.

Conclusion

It seems that with carefully derived plant characters, illustrated by a combination of icons and explanatory text, even complex structures can be understood and correctly addressed even from laypersons. With this, we show that future design of traditional identification keys should not only focus on botanical terms, but also on the users and their current skill set. Improving the species knowledge and learning plant identification methods via apps or printed guidelines can be supported by intuitive icons, descriptions and questions that guide the user through the identification process.

Deep Learning in Plant Phenological Research: A Systematic Literature Review

/in , /by

Negin Katal conducted a systematic literature review to analyze all primary studies on deep learning approaches in plant phenology research. The paper presents major findings from selected 24 peer-reviewed studies published in the last five years (2016–2021). 

Research on plant phenology has become increasingly important because seasonal and interannual climatic variations strongly influence the timing of periodic events in plants. One of the most significant challenges is developing tools to analyze enormous amounts of data efficiently. Deep Neural Networks leverages image processing to understand patterns or periodic events in vegetation that support scientific research.

 

“[…]deep learning is primarily intended to simplify the very time-consuming and cost-intensive direct phenological measurements so far.”

 

Technological breakthroughs powered deep learning approaches for plant phenology within the past five years. Our recently published paper describes the applied methods categorized according to the studied phenological stages, vegetation type, spatial scale, data acquisition. It also identifies and discusses research trends and highlights promising future directions. It is freely available here: https://www.frontiersin.org/articles/10.3389/fpls.2022.805738/full

To understand how scientific research on phenology is done, the different methods to retrieve phenological data need to be clear:

  • Individual based observations are for example human observations of plants, cameras installed below the canopy or even reviewing pressed, preserved plant specimens collected in herbaria over centuries and around the globe.
  • Near-surface measurements cover research plots on regional, continental, and global scales and are done for example via PhenoCams, near-surface digital cameras located at positions just above the canopy, or drones.
  • Satellite remote sensing is done via satelite indices, such as spectral vegetation indices (VIs), enhanced vegetation index (EVI), and more.

Overview of methods monitoring phenology.

Key findings:

The reviewed studies were conducted in eleven different countries (three in Europe; nine in North America, two in South America, six in Asian countries, and four in Australia and New Zealand) and across different vegetation types, i.e., grassland, forest, shrubland, and agricultural land. The vast majority of the primary studies examine phenological stages on single individuals. Ten studies explored phenology on a regional level. No single study operates on a global level. Therefore, deep learning is primarily intended to simplify the very time-consuming and cost-intensive direct phenological measurements so far.

In general, the main phenological stages are the breaking of leaf buds or initial growth, expansion of leaves or SOS, the appearance of flowers, appearance of fruits, senescence (coloring), leaf abscission, or EOS. More than half of the studies focused either on the expansion of leaves (SOS) or on the flowering time.

Across the primary studies, different methods were used to acquire training material for deep learning approaches. Twelve studies used images from digital repeat photography and analyzed those with deep learning methods. The publication shares in-depth information of the different types of digital photography suitable to provide those training data.

Furthermore, it categorizes, compares, and discusses deep learning methods applied in phenological monitoring. Classification and segmentation methods were found to be most frequently applied to all types of studies, and  proved to be very beneficial, mostly because they can eliminate (or support) tedious and error-prone manual tasks.

Future trends in phenology research with the use of deep learning

Machine learning methods need huge amounts of data to be trained. Therefore, increasing the absolute number of collected data is one of the key challenges – especially in regions or countries that lack traditional phenological observing networks so far. The paper describes methods and tools that will become important levers to support this kind of research, for example:

  • Installing cameras below the canopy that automatically take pictures and submit them over long periods of time are one way to tackle that.
  • PhenoCams prove to be a new and resourceful way to fuel further research: With indirect methods that track changes in images by deriving handcrafted features such as green or red chromatic coordinates from PhenoCam images and then applying algorithms to derive the timing of phenological events, such as SOS and EOS. We expect many more studies to appear in the future evaluating PhenoCam images beyond the vegetation color indices calculated so far.
  • Citizen Science data from plant identification apps such as Flora Incognita prove to be a long-term source of vegetational data. These images have a timestamp and location information and can thus provide important information about, e.g., flowering periods, similar to herbarium material.

We see that the study of phenology can easily and successfully exploit deep learning methods to speed up traditional gathering and evaluation of information. We, as a research team, are very proud to be a part of that and invite you to play a vital role – in using Flora Incognita to observe the diversity and change of biodiversity around you.

Can grasses be identified automatically via smartphone images?

/in , /by

Couch grass or ryegrass? Grasses are considered species, that are difficult to identify. The couch grass (Agropyron repens) is feared and often controlled and in gardens. Ryegrass (Lolium perenne), on the other hand, is the basis of many lawn seed mixtures and is a valuable forage grass. The question is: Can you even differentiate them? In our recently published paper, we investigated whether grasses can be automatically recognized and distinguished despite their great similarity. We wanted to know which perspectives are suitable and whether this would even possible without flowers present.

We studied 31 species using images of the inflorescence, the leaves and the ligule. We found that a combination of different perspectives improves the results. The inflorescence provided the most information. If no flowers are present, pictures of the ligule from the direction of the leaf are best suited to distinguish the grass species. All images were taken with different smartphones.

What do we learn from this experiment for our plant identification app Flora Incognita? Even more difficult groups can be well identified automatically, provided suitable images of the correct plant parts are provieded. These newly gained insights will be incorporated into the further development of our app.

In our experiment, we achieved > 96% accuracy for the 31 species when combining all perspectives. We also gained many, many training images that will significantly improve the reliability of the Flora Incognita app for grasses in the future.

Flora Incognita demonstrates high accuracy in Northern Europe

/in , , /by

The Flora Incognita project aims to inspire people – to get to know their (botanical) surroundings better, but also to think outside the box and reflect on the possibilities of artificial intelligence, deep learning or biodiversity. A great example of this is what Jaak Pärtel did: As a student project, he investigated the accuracy of the Flora Incognita application in Estonia, Northern Europe and even published a paper about it! With this exceptional project, Jaak won the Estonian National Youth Science Competition! Congratulations, Jaak! Here is a short interview, to share more details.

 

Hello, Jaak, congratulations on your first place in the Estonian National Youth Science Competition. Would you have imagined that happening when you started the project?

I honestly had no idea about what my project would become in a year. However, I was certain from the beginning that I want to do something that would not be “just another student project”. I got very positive reviews for the project in school, so I thought I would give it a try in the national competition. I was really surprised when I heard the results for the competition. Even that was not all, as I have published a scientific article (co-authors Jana Wäldchen and Meelis Pärtel) based on the project’s dataset and will represent my country in the European Union Contest for Young Scientists 2020/2021 this September.

How did you get the idea to do this project?
My two interests were life sciences and technology, so I found a suitable combination of the two. I had heard of plant identification apps but was not sure how  I wanted to have a field works experience and collect an extensive dataset to analyse it statistically.

Can you explain briefly what you investigated and how you went about it?
I investigated the accuracy of the plant identification applications Flora Incognita. I conducted the study in two parts: one with 1500 plant images from a database and second with 1000 observations in Estonian wilderness. I also investigated whether plants with flowers were identified more accurately and how much time automated identification took compared to traditional methods.

What are your main results in the project?
The main result of my project was that both applications reached close to 80% in accuracy in Estonian field conditions, with the correct species among the top five suggestions in circa 90% of the observations. In field conditions, plants with flowers were identified considerably more accurately than ones without them. Automatic identification took one minute compared to over four minutes for manual identification. During my project, I also translated Flora Incognita into my national language – Estonian.

What were you telling bypassers when they saw you documenting flowers?  :-)
I had no such situations, as most of my field works took place in locations with little populace. However, I would have said that I am a researcher collecting a dataset about plant apps. A surprising number of people have at least heard about the apps and would probably understand my mission in the field.

What are your next plans?
As of now I am serving my country in mandatory conscription service but after that I will start my Bachelor’s studies of Biology and nature conservation in University of Tartu. I would like to pursue science as a carreer and use innovative and computational methods in biology.

Digital beekeeping to learn and play

/in , , /by

With the “beeactive” app from the Würzburg Bee Research Association, children and young people can playfully learn more about bees and the biodiversity of various wild plants in their environment. The aim is to bring nature conservation and species protection into focus and to broaden their awareness of this. Flora Incognita provides the automatic identification of plant species as an important game content of “beeactive”.

The core principle of the app “beeactive” is the playful accompaniment of the virtual beekeeper Melli Fera and thus the establishment and care of digital bee colonies. Users can place individual beehives on an interactive map and search the real surroundings of the bee colony for flowering plants within a certain radius. The plants found are then automatically identified directly by the app. In this way, the virtual bee colony is supplied with pollen and nectar and the users can expand their knowledge of the species at the same time. The higher the number of plant species found, the better the digital bee colony develops and new hives may be added. In this way, users can also be motivated to sow their own bee-friendly flowering meadows. In addition, they support the creation of local and regional flowering maps with the numerous plant photos. The game is supplemented by a wide range of information on the ecology of honey bees and wild bees, as well as on the basics of ecological relationships. An integrated quiz allows direct application of the new knowledge and consolidates what has been learned.

For more information, please visit the following website: https://beeactive.app/.

 

The app “beeactive” was developed by Porf. Tautz and Florian Schimpf and financed with funds from the Bayerische Sparkassenstiftung. It is available free of charge in the Google Play Store and the Apple App Store.
