I apologize for the severely delinquent agenda for tomorrow’s SR meeting at Duke Farms.   As with many of you, things have been quite hectic with spring arriving and it slipped my mind.  Anyway; here it is:

10am-  Quick overview of DF.  Where we were and where we are and how we got there.  (in classroom)

10:30-  Begin tour of facility (start at Farm Barn Orientation Center –briefly discuss the sustainable features)-  Walk to Hay Barn to jump on Tram to see the 640 acre park and restoration practices

Discussing success and setbacks etc.

11:30-12:00 Return to FB

I am not sure how long these meetings usually are scheduled for but if some would like to see some of the western conservation grasslands, we could caravan out there to see some of that as well.

For directions to the Orientation Center at the Farm Barn click here.

The classroom, where we will meet, is on the first floor of the Farm Barn.

I have also attached a peer-reviewed article on evaluation of organized hunts in suburban “habitats”  that we might discuss during the day.

I look forward to seeing everyone tomorrow and again, my apologies for the tardy agenda.

PSI Master Class: A Rose By Any Other Name… Identifying Rosaceae

Tuesday, April 16th, 9:30 am to 12:30 pm

@ Bowman’s Hill Wildflower Preserve

Members: $30 Non-Members: $35

Dr. Ann Fowler Rhoads, instructor

In the Pennsylvania flora the Rose Family is made up of 28 genera (144 species) of woody and herbaceous plants.  Growth form ranges from canopy trees in the forest to common wildflowers of fields and woods.  Flower and fruit form vary primarily by the degree of fusion in the ovary and its placement with respect to other flower parts.  In PA the family includes 1 federally listed threatened species and 18 that are tracked by the Pennsylvania Natural Heritage Program.

While species identification in many Rosaceae genera is straightforward, others including the shadbushes and hawthorns provide an ongoing challenge because of the processes such as apomixus (seed production without sex).

The Rose Family is important to wildlife through the processes of pollination and seed dispersal.  It also includes important fruit and ornamental crops.

We will try to understand what holds the family together as well as the characteristics that allow us to recognize individual genera and species.

An Introduction to the Plant Stewardship Index for Land Managers

January 23rd, 2013. 10:00 am – 12:00 pm. FREE

In case of severe winter weather, snowdate is January 30th, same time.

The Plant Stewardship Index is a crucial tool designed for land managers to monitor, assess, and communicate the health of wild plant communities and the success of stewardship and restoration initiatives.

In this free class, we’ll introduce the basics behind the Plant Stewardship Index and discuss its use in comparing the natural values of different sites and for assessing change over time.

Topics will include use of the free online PSI Calculator, using PSI metrics to communicate the integrity of wild plant communities, plant survey basics, and designing more advanced surveys using transects and quadrats.

The class will be given by Jared Rosenbaum, Plant Stewardship Index Coordinator at Bowman’s Hill Wildflower Preserve.

Location: The Classroom at the Duke Farms Orientation Center, 1112 Duke Parkway West in Hillsborough, N.J.

To Register: Call Bowman’s Hill Wildflower Preserve at (215) 862-2924 or e-mail by January 21st, 2013.
