Ecology and Management
Holtwood is managed for its habitat being of highest and best use. A section of the Conestoga Trail traverses the property to connect Pollinator Park at Kellys Run Nature Preserve to Face Rock Overlook.
A highlight of this preserve through the summer is the number of pollinators such as butterflies, moths, and bees that can be found searching for nectar and pollen sources on native wildflowers and other plants. The Butterfly Club of Lancaster County has over two decades of data tracking the number and kinds of butterflies that can be seen on this preserve. Favorite butterflies include the rare monarch butterfly that feeds on milkweed, zebra swallowtail that feeds on pawpaw trees, painted lady that feed on asters and legumes, and a variety of skippers that depend on wild indigo, native grasses, and different kinds of plants for their life cycle.
Where there are an abundance of butterflies and other insects you can be sure to see a diversity of birds who feed insects to their young through the breeding season.
Holtwood drains into Tobe Run, a direct tributary to the Susquehanna River.

This preserve was acquired as part of a nationally recognized landscape protection project known as the PPL Project. Funds for that Project were provided by the PA Department of Conservation and Natural Resources, The Conservation Fund, Lancaster County, York County, PPL, Talen Energy, and Brookfield Renewable. The tracts that form the Holtwood Nature Preserve were donated by PPL and Talen Energy.
