Abstract: Given that small populations are susceptible to extinction and inbreeding, a primary goal of reintroductions should be to maximize the initial rate of increase. We investigated how the rate of increase of newly reintroduced populations of artiodactyl species was affected by population characteristics, such as size, sex, and age structure. All populations >20 grew positively at a median r = 0.17, while several smaller populations declined. Small populations grew faster if they contained more mature individuals. Small, heavily female-biased populations were more variable in r than those of a more equal sex ratio. These female-biased populations also grew on average less well. In sum, populations of <20 were more variable in r than larger ones and both age and sex structure explained a significant portion of this variation. In the experimental part of the study we used fallow deer (Dama dama) as a model species. We observed 2 experimental groups...
