CWM owns and
operates a commercial hazardous waste treatment, storage, and disposal facility (TSDF)
within the Towns of Lewiston and Porter. CWM contacted the NFWHC to find out about how
mowing practices on capped landfills can promote American songbird groundnesting. In
addition, over seven acres of mitigation wetlands were constructed in 1995. These two
programs foster habitat diversity at the Model City, NY facility.
A total of
approximately eight acres of wetlands were constructed, including one half mile of
footpath. The wetland area consists of one deep pond, two shallow ponds and one shallow
depression. The deep-water pond was designed to hold several feet of water and maintains
aquatic plants throughout the year. Vegetation consisting of approximately 5,000 trees,
shrubs, and plants of 21 species were planted. Most of the previously existing trees were
left untouched. During construction, existing natural materials were incorporated into the
wetlands. Soils removal during the initial clearing and grubbing were stockpiled and later
used as final cover for the new wetlands. Trees and other woody material cleared during
construction were chipped and used to create a system of walking trails. Shallow emergent
marsh and deep-water marsh, plant community types not typical of the facility, were
introduced with the goal of increasing biodiversity. The facility has installed bluebird
houses and is evaluating future improvements to this program.
acres of capped landfills and other grassed areas exist on the site. Starting in 1999,
mowing was postponed in these areas until after August 31st. The increased
grassland habitat will allow groundnesting birds the opportunity to raise their young in
these areas. The facility has plans to expand the grassland acreage in the future.
