Harp trapping has very limited applications. It is mainly used at sites where internal surveys are not safe and then only for determining species present during sampling. Some bats that swarm a site may not actually hibernate there, they may just be investigating the site as a backup in case their primary hibernacula inaccessible or unsuitable.
Costs vary depending on location, size, number of portals, and number of trap nights.
All state and federally listed species is professionally photographed for the record. This equipment is deployed where traditional trap techniques are physically impossible. Using this equipment, we have been able to show a lack of swarming activity near abandoned mine sites despite bats bing captured nearby in mist nets. Used in conjunction with mist netting or harp trapping, the night vision tapes produce unshakable proof of animal activity during sampling. After surveys are preformed, heavy equipment can be brought in to close the portal, and slumping of fill can lead to high long term maintenance costs.
