Abstract:

This report is an external evaluation of the current Swedish Action Plan for the Lesser White-Fronted Goose (2011-2015, extended until 2017) and parts of the Lesser White-Fronted Goose Project, commissioned by the Swedish Environmental Protection Agency (SEPA). The evaluation has come to the following conclusions: 1. The Lesser White-fronted Goose in Sweden is critically endangered and immigration from other populations, like the small Norwegian population, is not very probable. To secure the species from becoming extinct in in Sweden, larger resources are required than what is currently available in the system for action plans at SEPA. 2. An increased focus on breeding areas is recommended to obtain more data on predator activity, human disturbance and recruitment of released birds from the breeding program. 3. An increased control of the red fox (Vulpes vulpes) population in the breeding area during late winter, and an evaluation of the optimal ratio of released to wild birds in the population, are two highly prioritized actions. 4. Establishing a systematic monitoring program including quality control will make estimates on population development more reliable. 5. Potential breeding areas, with special emphasize on the extent of grazing fields, should be surveyed in the proximity of the present breeding area to estimate the possibility of natural expansion into new areas. 6. The captive breeding and release is well organized and of high quality. (However, as stressed above, an estimate of the optimal numbers of released birds into the wild should be evaluated.)
