Abstract

Local, short- to medium-term studies make clear that white-tailed deer can greatly suppress tree growth and survival in palatable tree species. To assess how deer have broadly affected patterns of tree recruitment across northern Wisconsin, we analyzed recruitment success in 11 common trees species that vary in palatability across 13,105 USFS - FIA plots sampled between 1983 and 2013. We also examined how recruitment in these species covaried with estimated deer densities here. Saplings of five palatable species were scarce relative to less palatable species and showed highly skewed distributions. Scarcity and skew provide reliable signals of deer impacts even when deer have severely reduced recruitment and/or no reliable deer density data are available. Deer densities ranged from 2.3 to 23 deer per km2 over a 30year period. Sapling numbers in two maples (Acer) and aspen (Populus) with intermediate palatability declined sharply in apparent response to higher deer density. Path analysis also reveals that deer act to cumulatively depress sapling recruitment in these species over successive decades. Together, these approaches show that deer have strongly depressed sapling recruitment in all taxa except Abies and Picea. As these impacts are now propagating into larger sized trees, deer are also altering canopy composition and dynamics. The tools developed here provide efficient and reliable indicators for monitoring deer impacts on forest tree recruitment using consistent data co…

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Patterns of consistently insufficient regeneration or altered species composition call into question the long-term viability and resilience of forest ecosystems.

    “The regeneration layer is therefore a primary indicator of forest response to canopy disturbance, and patterns of consistently insufficient regeneration or altered species composition call into question the long-term viability and resilience of forest ecosystems (Bradshaw & Waller, 2016;Russell et al., 2017).”
  • In severe cases, chronic deer browse pressure leads to widespread regeneration failure, where tree seedlings are unable to persist long enough to recruit into the sapling and subsequent canopy layers, ultimately leading to forest canopy loss.

    “In severe cases, chronic deer browse pressure leads to widespread regeneration failure, where tree seedlings are unable to persist for long enough to recruit into the sapling and subsequent canopy layers, ultimately leading to forest canopy loss (Bradshaw & Waller, 2016;McWilliams et al., 2018;Webster et al., 2018).”
  • Bradshaw and Waller (2016) corroborated this pattern of high-intensity deer browse and preferential browse on more palatable species as the dominant forces that control regeneration patterns across large regions of the eastern United States.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
