The present report presents a simple, yet efficient bat monitoring scheme for Central Espoo (southern Finland), which is based on the efficient use of ultrasound hand-detectors, well designed point counting network, and work of experienced bat scientists.
The point counting method (PC) implemented in this study has been widely used in Europe over the past 20 years. It gives the best results in northern parts of Europe, especially in towns, where bat species present can be firmly identified to species level on most occasions, using only the diagnostic characters of sonar calls.
In recent years, bat scientists have made a significant step forward: beginning with the present report, the sibling species of small Myotis (namely, brandtii and mystacinus), relatively common in forested areas of Europe, can be also identified to species level on many occasions. This has not been possible for decades, making the results of detector-based bat studies vague. But from now on this is possible! So I advise to use this unique possibility, and include similar bat monitoring schemes in bat monitoring programmes of European countries.
The easiest way to do so is by contacting the author of this report.
