Tennessee Invaders Part IV

There are almost 500 non-native plants that now call Tennessee home. These plants threaten native Tennessee ecosystems. Detection and monitoring, of these species present tremendous challenges to conservation groups. As a first line of defense, organizations such as the Tennessee Invasive Plant Council (TN-IPC) work to list and rank non-native species. Up until recently, organizations such as these have relied heavily on expert opinion and experience to rank non-native species. However, with the onset of metadata technology, the ability to access large amounts of information has transformed the ways in which we might enhance our understanding of the threat non-native species pose across the landscape.

This expedition will assist University of Tennessee at Chattanooga graduate student Courtney Alley in collecting data for her thesis research that will utilize this advancement in technology to further our understanding of non-native plant species.  Ultimately, this information will be used to map the locations of these invasive plant species and eventually determine a pattern of spread throughout the state. With your help, we can use these data to develop more effective detection and monitoring techniques for non-native plants!

I would like to thank all the citizen scientists who have worked to complete these expeditions!  Even though this is the fourth Tennessee Invaders we have almost 300 species left until we have transcribed all the herbarium specimens for non-native plants in Tennessee!  Keep up the hard work!

Label Babel

The Notes from Nature team has been thinking a lot about how to take some bold next steps to make transcription faster and better. To that end, we have launched something of an outlier expedition. This new expedition, which we have called “Label Babel” asks for help delineating the main label on herbarium sheets, which is usually – but not always! – in the bottom right corner. We also are asking you to tell us if the label is “all typewritten”, “all handwritten” or “both handwritten and typewritten”.

So you might be thinking “Why is Notes from Nature asking you to do this?” The short answer is that we think we can use machine learning approaches to detect where a label is, and the type of content (handwritten, typewritten, both) on the label. Your work helps us develop a training dataset for this machine learning effort. If we can indeed build this machine learning approach, it would allow us to have a quick way to sort different herbarium sheets and use the right Optical Character Recognition or Handwriting Detection Tools depending on the label.

We hope this is a fun diversion from the usual task and that the work you are doing here can help us build a better Notes from Nature. We will let you know how we do building the machine learning tools from the initial efforts here as soon as we can.

Another successful WeDigBio

wedigbio

WeDigBio 2018 was a great success! There were many productive onsite events. For example, the Field Museum welcomed over 400 people during this years WeDigBio! Notes from Nature received over 16,500 transcriptions during the four day event period. We also saw a lot of pre- and post- event activity which resulted in over 24,000 transcriptions during a one week period!

We want to thank the WeDigBio organizers, all the event hosts and most of all the volunteers that participated onsite or online. A special mention goes out to Notes from Nature volunteer am.zooni who is always willing to help in so many ways. We also want to thank the Zooniverse team for always keeping things running smoothly during times with such heavy site traffic.

We are already looking forward to WeDigBio 2019! In the mean time we have lots of great expeditions that need attention.

WeDigBio 2018 Day 4 summary

We closed out WeDigBio 2018 with 2,835 transcriptions! That put us at 16,865 transcriptions for the entire event. This surpassed our goal of 16,000.

We saw two expeditions with over 700 transcriptions during day 4. These were Fantastic Ferns! Celebrate Field Museum’s 125th Anniversary by Unlocking Tropical Diversity from the Caribbean, Africa and Australasia with 758 and Geography: US State Spotter — Lost Legumes (II) with 740.

There are still 19 great expeditions to work on! Two are currently above 90% and could use some effort to bring them to completion.

Total for WeDigBio?

We are in our final hours of WeDigBio 2018 and we hope that we can get to 16,000 transcriptions for the event. At the time of posting we are just over 15,000.

Please take a few minutes and help us reach our goal of 16K (or maybe even more)!

There are still 19 great expeditions to work on! Every single transcription helps us reach our goal!

WeDigBio 2018 Day 3 summary

WeDigBio 2018 day 3 was another big one at Notes from Nature. Notes from Nature received 2,727 transcriptions which is way above our daily average. So far we are over 14,000 transcriptions for the entire event!

We saw four expeditions with over 200 transcriptions during day 3. At the top were the Fantastic Ferns! Celebrate Field Museum’s 125th Anniversary by Unlocking Tropical Diversity from the Caribbean, Africa and Australasia with 343 and Geography: US State Spotter — Lost Legumes (II) with 466.

WeDigBio 2018 Day 2 summary

WeDigBio 2018 day 2 was another huge success! NfN received 6,640 transcriptions. That is our second most productive day ever. We are anxious to see what happens in day 3.

We also want to give a special mention to the expedition with the most transcriptions during day 2. Plants of Arkansas: The Delta and Crowley’s Ridge Flora (Part IV) received over 1,460 transcriptions!
