Wagner Free Institute Land Management Class Questions part one : Deer Population and management in a Morris Park, Philadelphia

As part of our Land Management Class we were asked about formulating questions about the topic. These Questions were to be informally presented to scientists and experts on the subject.  This was a unique and rare opportunity to lay out as much as possible to this wonderfully assembled group of knowledgable folks and we worked very hard to do just that, assembling a whole host of questions and on-the-ground scenarios for our audience. We were also asked to come up with an experiment that could help in answering questions which we also created.

We had the most opportune moment to have assembled the staff of Philadelphia Parks and Recs Forestry division, Botanists from the Philadelphia Botanical Club, as well as a forestry Scientist from Penn State with decades of experience in urban Forestry, as well as knowledgeable staff from Bartrams Gardens, and the Wissahickon restoration Volunteers. This was a wonderful opportunity to present our questions and our research proposal, which could possibly be implemented in the Haddington Woods section of Cobbs Creek Park. We will present to you, our dear readers, our highly informal presentation in one section at a time as a blog post and post the whole work as a page. Enjoy the most informal presentation and please ask questions and comment!  Here it is:

Questions For the Wagner Institute Land Management class

By Sean Solomon and Isabelle Dijols

We will organize our questions into categories and finish our piece with proposals for easily implementable experiments based on connecting the dots of the questions peppered.

Living just one mile north of Haddington woods and having been active stewards of the adjacent Morris Park for 8 years, many of our questions bear relevancy to Morris Park and our observations and work (and lack thereof) there and apply to Haddington woods quite succinctly.

Deer:
Is there a simple and cost effective way to measure deer populations within standardized scientifically agree-upon quadrangles? Perhaps key plants could be used as signature estimators, such as Jewelweed or Mayapples (based on commonly occurring and frequently browsed)?

Would it make sense for Public entities such as the City of Philadelphia to hire private companies to measure and quantify the deer populations, to assess the damages being done, to create and implement a public awareness campaign that could ultimately lead to legislation that would provide the proper funding to effectively and consistently manage the Deer population that would both serve the well-being of the species and enhance the quality of the natural lands and human health?

What does it take to get good deer data and consistent culling as well as majority public understanding and support for reasonable deer management practices?

What is it really like for deer who are hungry and malnourished in Fairmount park? Is there a way to measure the suffering of the animal? Weight estimates, views of the eyes or other indicators of physical strain (such as ribs showing, or even analysis of scat or even dna taken from browsed plants) ? Hours spent eating at specific times of the day and night? How is animal suffering quantified and described in Scientific literature and can this be easily translated into digesteble media by the general public?

Does the U.S. Center For Disease Control monitor Lime-disease clusters and should the public be aware of them?

Is there a way to measure the damage done to an ecosystem, on a quadrant level, taking in as much data as possible about the plants, animals and insects by the overpopulation of deer? How about historical data collected about a specific site or measurable area? Are there species documented to have been extirpated by deer browsing or just extirpated without knowledge of the reasons?

What was the deer population like in different known periods dating back as far as possible using every known documentation as clues?

What are the ecological benefits of deer, historically assessed or just conjectural ( perhaps they created a better diversity of herbaceous plants by browsing ones that started becoming invasive, or prevented trees of one species from becoming overwhelming to other trees, for example). Is there a way to asses the ecological benefits of deer ( perhaps visiting and describing sites where deer are considered to be in“equilibrium” with other species)?
On top of that what are the ecological benefits of ticks? (food for Turkeys and other feathered creatures?)

Has the fictionalized Bambi made deer so romanticized in our culture to the point where it is often difficult to discuss deer in an un-charged manner or is there another reason? Could it be related to the fact that there was a time when deer were so over-hunted that they almost became extinct?
The very fact that the deer that did survive the 19th century could be a testament to genetics and evolution that may answer some questions as to why they are so adapted to the modern human arrangement of plants and habitats- Could the deer that survived the 18th and 19th centuries have been the ones that had the genetic make-up to overcome the obstacles placed by human encroachment and this is the very thing that is making up this specific genetic selection to be so successful? ( in different wording) Is there a way to measure that? Perhaps look at genomes of deer through the centuries and compare?

Could we spray something on invasive plants that deer like to get them to eat them over the natives ( Suggested by Susan from Wagner)?

Is there a good way to make this problem go away or managed causing the least suffering to the deer and to the humans who love them?

SPRING TIME-LAPSE VIDEO 2014: 61 DAYS IN 3 MINUTES; BLUEBELLS TO BLOOM AND THEN TO JUNE

THE IPOD TOUCH WAS SET UP TO VIEW THE BLUEBELL PATCH IN THE SIDE GARDEN ADJACENT TO MORRIS PARK. THE BLUEBELLS GREW AND BLOOMED, WENT TO SEED AND DESCENDED BACK INTO THE EARTH AS THE  COLUMBINES AND GERANIUMS ROSE TO PROMINENCE. WATCH THIS ALL PLAY ITSELF OUT IN HIGH SPEED MOTION WHERE  TWO MONTH’S TIME HAS BEEN COMPRESSED INTO 3 MINUTES!

As the video reaches its last minute, pay attention to the lower right hand area, where you will see the Jack-In-The -Pulpit rise out of the Earth from its bulb in a rapid fashion and spread its leaves and bloom in a quickened pace compared to the other plants. Interesting how bulbs grow in relation to non-bulbous plants. The Ostrich ferns are also interesting to watch unfurl and rise up. Yes, one of them was removed and transplanted. At the very end of the video a Clematis vine is swinging itself into the picture, looking for something to grab onto.

The original intention of the video was to document the rise and blooming of the Bluebells (Mertensia virginica). After they lost their flowers, the scene was unfolding in such an interesting manner that we decided to let the camera keep rolling. Other plants that are featured in the video that you can keep an eye out for are Wild Ginger, (Asarum canadense) Lonicera sempervirens, The Coral honeysuckle and Mayapple, (Podophyllum peltatum).

For those interested in the process, we used the O-Snap App and had the Ipod take a picture every twenty minutes for the first 40 days and then every two hours after that. The night pictures were deleted because they distracted from the story of the plant’s progression and continuity of the video.

 

Garlic Mustard 2014, Morris Park, Philadelphia

Are you tired of seeing Garlic Mustard? If so please visit our stewardship area of scope in Morris Park, Philadelphia, where you will see no Garlic Mustard. If we are around we will gladly give you a tour. If not, just walk along the trail starting at the end of Morris Park Road  and you will not see any Garlic Mustard. Enjoy your walk and appreciate the wonderful variety of native, localized species of trees, herbaceous plants and shrubs in this once degraded patch of urban Forest! It’s been since 2006 that we started working on the infestations of Garlic Mustard in Morris Park. We have kept up with the efforts, yearly pulling in the same sites that we started at and expanding our area of scope to the point where we are satisfied with our  progress, ever mindful of our limitations.

Next: the alternate opening to this 2014 Garlic Mustard update:

Garlic Mustard: You cannot just pull one. Once you start it, you cannot stop year after year, area by area, and if you do not pull it out one year you will be canceling out the many hours of  your work during the previous years.  This is the reality of the seed bank depletion method of invasive control.  Harsh as this may sound, this is a biological reality in the world of managing and controlling plants.

This is Alliaria petiolata, the Garlic Mustard.

So it’s been a long nine years removing Garlic Mustard from this site. What is our motivation? Why do we do it? What has changed and evolved on the site and will we keep doing it? How many hours have we spent?

Our motivation is experimental and hopeful at the same time. We started out believing that removing Garlic Mustard was  the thing to do. We continue to do it as we see the fantastic results. It really makes a difference.

The Oaks (note the one above) and other trees are seeding themselves in and have enough of an advantage to continue to grow.  More and more herbaceous native plants are growing in once invaded areas. There is less and less Garlic Mustard to pull every year, freeing ourselves up to do other things like visit other places or work on the garden. This year we pulled and trashed 31 bags, Last year we did 78 bags. This year about 30 hours of time spent.

We hope to inspire anyone out there with Garlic Mustard to keep up the work, and be realistic in your area of scope so you can continue to go back year after year and follow through on depleting the seed bank. If anything you will learn your area and the habits of this plant quite well and have fun doing it!
