Climate and Ecological Data

The region in the vicinity of the Louis Calder Center is highly glaciated, creating a lake district of more than 500 lakes and ponds within a 10 km radius. The station itself is situated on highly metamorphosed bedrock (gneiss, schist) at elevations from 145 to 200 m, with shallow soils: 25-50 cm of sandy loam in the Hollis association.

The climate is coastal-mesic, with annual mean temperature and precipitation of 10.5° C and 112 cm, respectively.

The field station comprises 113 forested acres with a variety of ecosystems and communities available for study, including:
  • Mixed deciduous forest. The forested vegetation is typical of mid-successional forests in the Mid-Atlantic region. Northern Red and Black oaks dominate the canopy. The understory is composed of late-successional species including Sugar Maple, Red Maple and American Beech. Stands of Eastern Hemlock occur in shady areas.
  • Mesotrophic lake. The 10-acre seepage- and spring-fed Calder Lake supports diverse plant communities.
  • Wetlands. Small ponds, streams and wetlands with skunk cabbage, cattail, arrowhead, and wild rice are habitats for many animals.
  • Old fields. The station maintains small (1-2 acre) patches of old field that are typical of the ecosystem mosaics in southern New York.
The faculty at the Calder Center are in the process of making our climatological and biological data sets available to other scientists. Currently, the following data are available:
