Watershed Conservation Plan (WCP)
In 2004 the Darby Creek Valley Association completed work on a WCP for the Darby Creek Watershed with the assistance of Cahill Associates under a grant provided by the Pennsylvania Department of Conservation of Natural Resources and the Delaware County Council. The report is in Adobe Acrobat PDF format in 12 separate files with links to them below.

Haverford State Hospital Ecological Assessment
In 2002, Haverford Township acquired the 209-acre former Haverford State Hospital site in Haverford Township, northeastern Delaware County, PA from the state and permanently protected 124 acres for passive open space recreation. In 2007, Natural Lands Trust and Princeton Hydro with funding and support from the National Fish & Wildlife Foundation, Haverford Township Board of Commissioners, Haverford Reserve developers Todd Pohlig, Pohlig Builders & Goldenberg, Darby Creek Valley Association, Bryn Mawr College, Math Science Partnership of Greater Philadelphia, the Quadrangle and the Ad Hoc Haverford State Citizens Advisory Board prepared an Ecological Assessment to identify the challenges and opportunities for the sustainable, but primarily passive, use of the natural areas.

The Assessment report (at the bottom of this page) describes upland and wetland vegetation on the site and the results of surveys of selected terrestrial wildlife, fish, and macroinvertebrate species. Based on these biological inventories, the Assessment identifies threats to the natural features on the property and describes the ecological condition of the site and its value to the surrounding Darby Creek Watershed.

Introduction 

Ecological Assessment and Action Plan for Sustainable Stewardship:
A 2 page “Handout” is an Executive Summary of the Ecological Assessment and it includes major recommendations along with photos.

 

The “Report” describes the site:
* A 20-60 year-old red maple terrestrial forest encompasses 75 percent of the natural area and is moderately impacted by a variety of common invasive plant species. The oldest portions of the forest, mixed hardwoods along North and South Brooks, are the least impacted by invasive plants. Highly impacted areas are forest openings and utility rights-of-way.
* The “Meadow,” located in the northern portion of the site, contains old field/ terrestrial meadow species representing an “uncommon native plant community.”
* South Brook has a more balanced fish community structure than North Brook for stream health with increased fish density, the addition of a large fish (American Eel), and more complete colonization. This appears due to the low stream flow and high sediment influx in the upper reaches of North Brook and the effects of a small steel culvert that impedes storm flow and fish migration.

Haverford Township Commissioners, Haverford Township Recreation Department and volunteers will be using this Assessment to guide future decisions and actions for:

 

* Removing invasive plants,

* Managing deer population at the property

* Designing trails and maintaining the natural areas

* Involving citizens in preservation, restoration and

* Enjoying the protected green space....

 

This ecological assessment and action plan conducted by Natural Lands Trust (NLT) was part of a bigger project. A group of volunteers wrote a grant in 2006 that was funded by National Fish and Wildlife Foundation.

 

In addition to the volunteers writing an RFP (Request For Proposal), and hiring Natural Lands Trust (NLT) to conduct this assessment and action plan, the project led to:

  • The planning and implementation of The South Brook Trail;
  • Educational plans for grades K- 12 including educators developing lessons around the Darby Creek and natural areas; also
  • Equipment installed for students to take direct readings of the South Brook and weather in the Meadow for analysis and educational exploration.

This project happened because of an outstanding team of volunteers – see below.

 

Many thanks to Darby Creek Valley Association for assisting in the grant project and for hosting this information and report…

Delaware County's Darby Creek Greenway Plan
The Delaware County Planning Department developed a County greenway plan for the Darby Creek watershed within Delaware County. This plan is based on recommendations in the Delaware County Comprehensive Plan and will be adopted as a component of that plan and as a section of the upcoming Delaware County Open Space, Recreation, and Greenways Plan. This watershed-specific greenway plan is a prototype document that will serve as a model for future development of an additional greenway plan encompassing the remainder of the County. More informtion and the plan are available at the County's website: www.co.delaware.pa.us/planning/environmental/greenwayplan.html
