The Conservation Reserve Enhancement Program was developed to accomplish multiple goals. CREP is designed to improve water quality, benefit wildlife through habitat development, and reward participants for doing their part to help the environment. All landowners can apply for CREP! Non-forested land along waterways and highly erodible land (HEL) are target areas for CREP enrollment.

Stream health is dependent on many factors in the water and along the banks. Water quality and temperature play an important role in determining what can live in a stream. The trees, shrubs, and plants that grow in this area along the stream, known as a riparian corridor, serve a dual purpose. This vegetation helps control water chemistry and temperature, and provides abundant habitat for wildlife. Establishment of wetlands and grasslands also play a role in water quality and wildlife habitat.

Stream Ecology Impacts

  • Nitrates and Phosphates ~ Nitrates and phosphates are naturally occurring nutrients in the environment; however, excessive amounts of these nutrients can be harmful to waterways. These nutrients can induce large algal blooms, which die over time, and through decomposition use up large amounts of valuable oxygen. Nutrients enter waterways through excess water runoff and erosion of unprotected soil.
  • Sedimentation ~ Sediment consists of tiny particles of soil and organic material. Sediment enters waterways through excessive soil erosion; sediment particles cloud water, increase stream temperature, and commonly transport additional contaminates. These particles also gather along the streambed, covering the habitat of bottom-dwelling aquatic life.

CREP has a list of conservation practices that have been created to meet both environmental needs and the desired request of the landowner. These practices can be discussed with a CREP planner, who visits the property where CREP will be implemented.

CREP Helps with Water Quality & Wildlife Habitat Development!

Riparian corridors, wetlands, and highly erodible lands (HEL) enrolled in CREP are allowed to revert to their natural state, and may be helped along in this process with the planting of native trees, shrubs, plants, and grasses. These “wild”-looking vegetated areas stabilize soil and act as natural filter strips for runoff. Additionally, as the riparian buffer matures, the stream becomes shaded by vegetation, helping control stream water temperature. Through CREP, new wetlands can be constructed in cultivated areas where soil tests indicate that a wetland existed in the past. These wetlands control flooding and wetland plants help remove water contaminants. A unique feature of these areas is that the resulting vegetation is specific to riparian corridors, wetlands, or grassland habitats.

A variety of wildlife depends on grassland habitats and adjacent riparian areas year-round. Birds use the many layers of vegetation cover (trees, shrubs, and grasses) and plentiful plant species found in these habitats for food and cover. During the breeding season, many ground-nesting bird and mammal species build nests in the vegetation and use the cover to raise and protect their young. In the winter, seeds are foraged and dead vegetation creates pockets where ground-dwelling birds can take shelter. Butterflies, and other enjoyable insects, feed on the flowers that grow in the grassland. Unlike the specific vegetation of riparian corridors, wetlands, and grasslands, the wildlife that depend on these areas commonly travel between them for both food and shelter.

Enrollment Rewards!

Congratulations! You are now taking part in one of the premier conservation programs in Pennsylvania! Not only are you being environmentally friendly to water quality and wildlife habitat, you are being financially compensated for your good deeds. Remember, your responsibilities don’t end with CREP Conservation Practice installation. You must keep your CREP practices in good working order for the entire term of the CREP contract. But don’t worry – if you stay involved during the development of your CREP Conservation Plan and play an active role in understanding your responsibilities, you will be equipped for success! Also, there are many federal, state, and local partners available to help you with the technical details of CREP, from maintaining tree seedling health to caring for newly installed wetlands. By calling the toll-free number at the bottom of this page you can hear a list of the CREP partners and get the phone number for your local CREP contact.
