<strong>EUROBATS</strong>: 15 years helping bat<br />

conservation in Portugal<br />

by Luísa Rodrigues<br />

The Portuguese bat fauna includes 26<br />

species, 24 in the continental part of<br />

Europe. According to the new IUCN<br />

criteria, in the continent there are three spe-<br />

cies critically endangered, one endangered<br />

and five vulnerable.<br />

Since 1967, Portuguese law has protect-<br />

ed all bat species. They are also covered by<br />

international legislation, such as the Bern<br />

Convention, the Bonn Convention, and the<br />

EU Habitats Directive.<br />

The actual list of Portuguese Special<br />

Areas of Conservation (SACs) includes the<br />

majority of important underground roosts;<br />

some areas also include feeding habitats.<br />

In 1987 the Universidade de Lisboa and<br />

the Instituto da Conservacao da Natureza<br />

started a project to obtain the data required<br />

to prepare a National Cave Bat Conservation<br />

Plan. This project included: a) an inventory<br />

of roosts, b) seasonal vis<strong>its</strong> to the most<br />

important roosts to determine their occupation<br />

throughout the year, c) monitoring<br />

of those roosts, d) tagging of some of the<br />

most common species to map the movements<br />

and distribution of the various populations<br />

and to identify the network of roosts<br />

on which they depend.<br />

The project culminated with the publication<br />

of the Plan, in 1992. This document not<br />

only included the basic biological background<br />

required to preserve our cave-dwelling<br />

bats, but it also identified a strategy for<br />

their conservation. It included recommen-<br />

dations on specific roost protection measures<br />

(including the consolidation of the<br />

ceilings and walls of unstable roosts, clearing<br />

of the flying paths in roosts that can be<br />

blocked by falling stones, partial clearance<br />

of the vegetation that tends to block the<br />

entrances of some roosts, removal of inappropriate<br />

gates, and construction of fences<br />

in the entrances of some roosts), relevant<br />

lines of research, public education, and legislation.<br />

This strategy has defined most of<br />

the conservation work that has been carried<br />

out since <strong>its</strong> publication.<br />

In 1994, co-financing by the LIFE Programme<br />

and Instituto da Conservação<br />

da Natureza allowed the extension of the<br />

conservation work to the poorly known<br />

non-cave-dwelling species. The first priorities<br />

were to study their distribution in nine<br />

natural parks and reserves and to obtain<br />

some information on habitat use in these<br />

areas; this project involved the search of<br />

roosts, mist-netting and transects with batdetectors.<br />

It provided some useful data on<br />

the status of these species and allowed the<br />

preparation of preliminary recommendations<br />

for their conservation. Later on the<br />

study was extended to four other natural<br />

parks and several reserves. This project also<br />

allowed us to start a line of research related<br />

to one critical aspect of the conservation of<br />

cave-dwelling bats — the identification of<br />

the feeding habitats in the most important<br />

underground roosts. Until now, useful data<br />
