The most common critters

We’ve finally wrapped up our data collection & collation.  Amazing to have over 900 camera-nights run across 60 different sites.  Almost half of these (27) were on back-yard chicken coops with the rest split evening between back yards without coops and nearby woodlands.

Below is a table of the wild animals most frequently detected on these cameras.

Grey Squirrel Raccoon Cottontail Opossum Deer Gray Fox
Sites 46 27 16 15 14 14
Pictures 933 221 127 86 178 39

And here are a few photos, and notes about each species.

Help us launch eMammal, run camera traps in western North Carolina

Chicken coops were a warm up for the main event, eMammal, a new citizen science camera trapping project in collaboration with the Smithsonian.  We will be prototyping our website and database with a select few volunteers this year from August – November in and around Stone Mountain and South Mountains State Parks/Game lands.  We will provide the camera traps if you are willing to put them into the woods at 4 different places over the next few months (moving them every 3 weeks).  See below for details, or open this eMammal Volunteer Recruitment pdf file.

We still have a few slots open, please contact ariewald@yahoo.com to sign up.

Citizen Science Camera Trapping in North Carolina

Welcome to eMammal – help us use camera traps to survey wildlife

Background:

We are using motion-sensitive cameras take short videos, triggering whenever a warm-blooded animal walks by, and saving these images to a memory card.  The cameras are silent, and use an infrared flash, so usually the animals don’t even know they are being photographed.  By volunteering for this project you will get a first-hand look at the forest animals, and help us collect important data for science and conservation.  You will be part of a larger team of camera-trappers led by scientists at the North Carolina Museum of Natural Sciences and the Smithsonian Institution, running a network of cameras across the east coast.

The data you collect will help us document not only what animals live where, but also how they are affected by consumptive (i.e. hunting, trapping etc.) and non-consumptive (i.e. hiking, biking etc.) recreation.

You will be one of the first participants in eMammal, and your feedback will help us prepare for expanded surveys in the future.

We Need Your Help!

We will be relying on volunteers to run the cameras at the different field sites.  Each volunteer will be loaned 3 camera-traps to use, complete with rechargeable batteries and memory cards.  We will also give the volunteers a set of GPS points where they will need to set the cameras (in the NC State Park or Gameland).  Most sites will involve some hiking with the potential for steep terrain.  In order to navigate to those points, volunteers will need to have their own GPS unit or Smartphone with GPS App, these will not be provided by the project staff.  Volunteers must also have access to a computer and internet to upload the pictures the capture to the eMammal website.

Each volunteer (or team of volunteers) will be asked to move the camera traps four times, in 3-week intervals, from August to November 2012.  At each location they will put out 3 cameras one on a hiking trail, one near (50 meters) to the trail and one far (200m) from the trail.  All three cameras will be set up on the same day, and left for three weeks at a time. At the end of the three weeks, the cameras will then be moved to the next location (doing this a total of four times over the 12 week period). Overall, the volunteer would need to go out five times into the forest to setup or retrieve the cameras. Weeks where cameras will need to be moved are below…

Tentative Camera Set Schedule:

1st Setup- Week of August 20th-25th

2nd Retrieve and setup- Week of September 10th- Sept. 15nd

3rd Retrieve and Setup- Week of October 1st – 6th

4th Retrieve and Setup- Week of October 22nd – 27th

Final Retrieve- Week of November 12th- Nov. 17th

Please be careful if you are working in the Gamelands, as hunting season for several species begins as early as September. There is no hunting in the State Park.

 

Training:

Each volunteer needs to attend a mandatory training before starting the project.  During this training, volunteers will meet the project staff and learn more about the project.  Volunteers will be taught how to use all equipment and computer programs required by the project.  Volunteers will also receive their three cameras, latitude/longitude points and other equipment and literature at the training.  Training will take 3- 4 hours.  You can attend either training regardless of what area you will be volunteering in and you only need to attend ONE training.

Mandatory Training (these dates are still tentative):

  • Sunday, August 19th at South Mountains State Park
  • Monday, August 20th  at Stone Mountain State Park

How to Sign Up:

We will be running cameras this year in four areas:

  1. Stone Mountain State Park
  2. Thurmond Chatham Gameland
  3. South Mountains State Park
  4. South Mountains Gameland

If you can commit to the schedule outlined above and have an interest in running cameras in one of these locations, please contact Arielle Parsons (ariewald@yahoo.com) to sign up.  Please indicate in your email which of the four areas above you would like to work in (also indicate if you are flexible) and which dates you are available for training (if you are not available 8/19 or 8/20, please indicate when around those dates you may be free).  We will send you a confirmation email shortly afterwards.

If you have any questions please contact Arielle Parsons (ariewald@yahoo.com), 919-610-6624.  Arielle can also be found in the Biodiversity Lab at the new Nature Research Center at the NC Museum of Natural Sciences in Raleigh.

Thank you for your interest and help getting the word out on the project! We are very excited to meet you all and get started setting up camera traps and catching some good pictures!

The landscape of our study

One of the goals of this study is to see which wildlife lives in different parts of a metropolitan area.  In particular, how much natural area do different species need to survive?  To ask this question, we need samples (aka places where we run a camera trap) across a variety of landscape types.  We were fortunate to have a wealth of volunteers help us run cameras all over the region.

Here’s a map showing where you helped us run cameras.

Black dots show where volunteers ran camera traps for us while colors show level of development from red (highly developed) to yellow (lightly developed) to green (natural).

 

To conduct our analyses we need to convert this map into numbers that we can use in statistical tests relating the animals we detected to the landscape.  We did this by simplifying the  National Land Cover dataset to natural, lightly developed, and heavily developed.  Then we use a Geographical Information System (GIS) to calculate the percentage of land around our sample point that is in the various landscape types. The below graph shows the results of this analysis.

land cover near our sample sites

The land cover within 500m of our sample sites in back yards with chicken coops (left), back yard without coops (center) and wooded sites nearby (right).

 

The graph shows that we sampled a nice diversity of sites for natural and lightly developed areas.  Now the next step is to see if the animal communities were consistently different in those areas. We are counting up the pictures now, and will post some results soon.

Drop by the lab, check out some fresh, hot camera trap pictures

 

As we collect the final cameras from our volunteer chicken coops we’ll have the fun job of looking through them identify what animals we photographed.   If you drop by the Biodiversity lab (2nd floor of the NRC) you might be able to give us a hand with this.  If we aren’t going through the latest finds, you can at least have a look at our greatest highs reel running on the monitor.

 

Who knows what critter will turn up next?!

Coop Research ‘Booming’

Our own Arielle Parsons was highlighted in a recent Raleigh News & Observer article on research at the Nature Research Center. 

Behind the globe, research booms in downtown Raleigh

BY CHELSEA KELLNER - CKELLNER@NEWSOBSERVER.COM

RALEIGH — Every day, Arielle Parsons heads to her laboratory at the Museum of Natural Sciences to conduct her research on chicken coop predators – with thousands of people watching.

She works in the Biodiversity Research Lab, and with 220,000 visitors streaming past since the doors opened in April through the end of May, she’s gotten to practice an unusually interactive breed of science.

“It’s nice to kind of have this interaction, because we’re doing citizen science here, and this way you know who you’re doing it for and who you’re doing it with,” Parsons said.

For museum-goers, the new Nature Research Center at the Museum of Natural Sciences is an exciting, hands-on place to visit, learn from and leave after a few hours. Parsons is just one of the researchers who help anchor the dynamic, real-world atmosphere by making the museum their scientific workplace.

Three times a day, in-house researchers give presentations in the giant globe of the SECU Daily Planet Theater. Every afternoon, the Window on Animal Health lures visitors to the second floor to see veterinary procedures in action.

Since the museum opened, it’s not just ticket sales that have been busy. Here’s a look at the research that’s been going on behind the iconic globe on West Jones Street.

Martian meteorite in the Astronomy Research Lab: They know it’s from Mars because the gases trapped inside have the same composition as the atmosphere on the red planet, said museum spokesman Jonathan Pishney. Thin slices show a beautiful mix of the minerals olivine and pyroxene. Researchers are also examining the Allende meteorite, a 4.6 billion-year-old relic from the start of the solar system.

Lemur armpit bacteria in the Genomic Research Lab: Yes, you read that right. Lemur expert Julie Horvath plans to investigate the particular biology of lemur armpits and compare the bacteria there to that found in humans and baboons. The idea is to learn more about the evolution of bacteria, how it behaves and how it ends up where it does.

Parsons’ work on chicken coop predators: She has recruited volunteer chicken-owners in urban, suburban and rural areas to set up remotely triggered camera “traps” outside the coops and in a separate control area nearby. Any moving animal triggers the traps, allowing Parsons to document the species and concentration of predators.

Analyzing the data will help determine whether chicken coops attract predators, as well as provide important information in case of rabies outbreaks in the area. That means sorting through hundreds of photos, but thanks to her unique glassed-in workplace, Parsons doesn’t have to do it alone. She sometimes invites visitors to help her look through the photos and catalogue the species seen – a collaborative process she calls “citizen science.”

“For myself, this means being able to investigate the potential power of citizen science for answering these questions,” Parsons said. “When you have the power of citizen science to help you, the data you collect can be massive, so you get more precise answers to your questions.”

Update from coop-central – raccoons at the hen house

Here at coop-central (i.e. the biodiversity lab of the NRC) we have been busy entering all the photos and data from the big grand opening event into a special database we created for camera trap data.  We also have a second batch of cameras out now on another round of coops.  Once these new cameras come back we’ll start posting some results.

Until then, I’ll post a raccoon picture from a recent backyard camera.  Raccoons seem to be the only species that are really interested in the chicken coops; we have some footage of them trying to break into coops, stealing eggs, and coming back night after night to some places.  In Raleigh, raccoons seem to be worse than the fox around the henhouse!

Highlight Video

Wow, what an amazing 24hr Grand Opening.  Thanks to all the Great Chicken Coop Stakeout volunteers who helped make it so successful by running a camera trap on their coop over the last month and then bringing the camera back during the opening.  Extra-thanks to the volunteers who helped us set camera traps in your yard over the last year, and, especially, staff the lab during the opening to help register what we found.

We got some amazing pictures, and learned quite a bit about what predators live in urban, suburban, and rural North Carolina.  We’ll crunch the numbers over the next week or two and present the results shortly.  In the mean time, below is a fun highlight video from the footage returned by volunteers.

(Thanks to Zena Brenner for making the video)
