Productivity measures of white‐tailed deer in New Hampshire: Assessing reduced recruitment  NL Fortin, PJ Pekins, KA Gustafson - Wildlife Society Bulletin, 2014
... recruitment rates based on indices from harvested deer have steadily declined since the mid-1990s... Pregnancy rates were 97% and 100% in the adult and yearling age classes, respectively, but few (8%) fawns bred. All pregnant fawns carried single fetuses, while yearlings averaged 1.72 fetuses and adults 1.95... Pregnancy rate and fecundity of older deer were unchanged since the 1980s; fawn pregnancy rate declined but was always relatively low. Productivity of the population increased due to a greater proportion of adults in 2011–2013, suggesting that declining recruitment may be due to increased summer fawn mortality.
