Native Trees & Shrubs that Benefit Wildlife

"Native trees, shrubs, and vines are the key to successful backyard habitats, offering critical food and cover to our wildlife.  Native vegetation  will thrive with the least amount of care. Non-native ornamentals require a great deal of care (watering, chemicals for insect pests, fertilizing) and tend not to thrive as readily as native vegetation.  This should be a prime consideration with successive drought years and water shortage problems.  Many non-native ornamentals have no food value to our wildlife.  Be sure to include native evergreens, key in providing cover year-round (safe refuge from predators and bad weather, safe nesting sites, and a safe place to roost through the night)."

Birds of Mountain Lakes

The Mountain Lakes Preserve is home to a diversity of birds, some common, some rare.  eBird is a website and an app in which people (both professional birders and non-professional) can report their exact sightings of bird species.  In the past few months, birders have reported sightings of many interesting species.  Below is a list of some species that call Mountain Lakes home, and where to look to find them.  This is only a fraction of the diversity that exists within the preserve. 

 Palmer Lake is home to a  Great Blue Heron  that is frequently seen on the dams or lake shores.

  Great Horned Owls  are elusive, but can be heard at dusk and dawn in the pine forest.

  Pileated Woodpeckers  often sound like a hammer hitting a tree when searching for food.  They can be found in Witherspoon Woods in large, dead trees.

  Cedar Waxwings  are fairly common if you know where to look.  They can be found along wood edges near a water source.

  Eastern Meadowlarks  can be found nesting on the ground of large meadows, such as Tusculum.

Janssen Cares Volunteer Day

Volunteers from Janssen Pharmaceuticals pulled on their work gloves and hefted trimmers, loppers, and chain saws to work with members of Friends of Princeton Open Space (FOPOS) recently. Their task was to get a start on ridding the area along the driveway of the Billy Johnson Mountain Lakes Nature Preserve in Princeton of some stubborn invasive species.

After a quick lesson by FOPOS Natural Resource Manager, Jeff Geist, in identifying the most prevalent invasives, (honeysuckle, grapevine, porcelain berry, and multiflora rose), the eight Janssen personnel enthusiastically tackled their assignment, undeterred by poison ivy and two areas of ground-nesting yellow jacket wasps.  In record time 250 linear feet on both sides of the driveway had been cleared.

Clark Lennon, FOPOS board member and supervisor of the day’s work, said he was impressed by the Janssen crew.  “I never thought we would get this much accomplished in just a few hours”, he said.  “They worked really hard and did a great job.”

FOPOS plans to remove invasive species along the full half-mile length of the driveway into the Nature Preserve with the help of volunteers and board members. This work complements the 18 acre forest restoration project on the west side of Mountain Lake which FOPOS has also undertaken.

Woodfield Reservation Update

This summer, the FOPOS Trail Crew has been hard at work restoring and repairing the trails at Woodfield Reservation.  Last year, the crew cleared several thousand feet of trails to make it walk-able.  This year’s project has been constructing boardwalks over swampy and wet trails.  Thus far, in June and July, the team had 9 workdays with a total of 14 volunteers resulting in 162 work hours, 360 feet of constructed boardwalks and 130 feet of relocated trails.

 

If you are interested in helping our volunteer crew for the remainder of the summer, and into the fall, please email us at info@fopos.org. 

FOPOS Hosts Princeton YMCA Outdoor Living Skills Camp

The Friends of Princeton Open Space hosted 36 kids from the Princeton YMCA Outdoor Living Skills Camp on Tuesday, July 18 from 10:00-2:00.  During their time here, the campers learned about, and practiced, Leave No Trace, the set of guidelines for all hikers, campers, etc.

 FOPOS Natural Resource Manager, Jeff Geist, and two summer interns, Anna Korn & Katrina O'Donnell, guided the group around the property.  During their 2 mile hike, the kids learned about tree identification, how to identify edible plants (they all loved wineberries), and the guides helped them with bird and other animal identification.  We rounded out the hike with butterfly and other bug collecting at the Tusculum Meadow.  

The group then enjoyed lunch at Pettoranello Gardens, followed by a brief lesson on outdoor first aid.  Finally, the group all created key chains to remind them of the 7 Principles of Leave No Trace. 

TIAA EarthShare NJ Corporate Green Challenge

On April 7,2017, TIAA Financial Services of Princeton, NJ participated in EarthShare's Corporate Green Challenge.  A large group of volunteers came out to the Mountain Lakes Preserve to assist in the construction of a deer fence.  The area was previously clear-cut in order to stage equipment for the restoration of the Mountain Lakes dam.  After the restoration was completed in 2012, the area was planted with native trees and shrubs. A deer fence was installed to prevent harsh deer browse on the newly planted natives.  After many years, the fence was in need of replacement.  That is where TIAA came in. 

A Day in the Mud

It was an interesting change from what has become a frequent pastime of building boardwalks everywhere.  A hardcore group of volunteers including Chris Coucill, Van Williams, Richard Meyer, Bob Shull, Clark Lennon and Ted Thomas finally got to work on a bridge at Roger's Refuge, which had slipped its footings and floated away.

Fortunately, it was also able to float back, with a little urging.  After quite a bit of dragging, prying, lifting and flipping, it was back in place and ready to face the next flood.  During the project, the group suffered 3 casualties: Clark, Van and Bob (pictured), in that order, slipped on a very slippery slope, and later had to be helped to their feet.

 Man down!
