Ecology, silviculture, and management of Black Hills ponderosa pine

Publications Posted on: June 22, 2020
This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem.

Review Process Information: Black Hills Timber Growth and Yield Draft General Technical Report

Pages Posted on: March 05, 2020
The USDA Forest Service Rocky Mountain Research Station is preparing a publication describing changes that have occurred in recent decades in the forests of the Black Hills. In addition to the normal technical and editorial reviews for publications, we are providing an opportunity for public review this publication. Comments were due in written form by May 1, 2020.  

The importance of disturbance and forest structure to bird abundance in the Black Hills

Publications Posted on: September 14, 2019
Many North American birds associated with forest disturbances such as wildfire and mountain pine beetle (Dendroctonus ponderosae) outbreaks are declining in abundance. More information on relationships between avian abundance and forest structure and disturbance is needed to guide conservation and management.

Black‐backed woodpecker abundance in the Black Hills

Publications Posted on: December 06, 2018
The Black Hills population of black-backed woodpeckers (Picoides arcticus) was petitioned, but deemed not warranted, to be listed as a threatened or endangered species under the Endangered Species Act and more information on their population size in the region is needed. Our objective was to map abundance and provide a population estimate of black-backed woodpeckers in the Black Hills and Bear Lodge Mountains of South Dakota and Wyoming, USA.

A modified tree classification for use in growth studies and timber marking in Black Hills ponderosa pine

Publications Posted on: February 12, 2018
A satisfactory silvicultural management of ponderosa pine stands requires a judicious selection of trees to be left in the reserve stand. The timber marker must know what type of tree has the greatest growth potentialities and what type of tree will respond but slightly upon being released.

Pumas affect elk dynamics in absence of other large carnivores

Publications Posted on: December 12, 2017
We investigated survival, reproduction, and population growth (λ) for a declining elk (Cervus canadensis nelsoni) population in South Dakota, USA, 2011-2015. We obtained survival data from 125 calves and 34 yearlings. We determined survival and pregnancy rates for 42 adults (2-8 years old) and 39 old adults (≥8 years old).

Thinning reduces mountain pine beetle-caused tree mortality

Science Spotlights Posted on: October 12, 2017
The mountain pine beetle is an important bark beetle associated with ponderosa pine in the Black Hills. Episodic outbreaks can result in extensive tree mortality compromising ecosystem services. Strategies are needed to mitigate mortality levels where appropriate. This study sampled stands ranging from 35 acres to 365 acres and were widely distributed across the 6,000 square miles of the Black Hills.  

Assessing temporal genetic variation in a cougar population: Influence of harvest and neighboring populations

Publications Posted on: November 18, 2016
The geography of the Black Hills region of South Dakota and Wyoming may limit connectivity for many species. For species with large energetic demands and large home ranges or species at low densities this can create viability concerns. Carnivores in this region, such as cougars (Puma concolor), have the additive effect of natural and human-induced mortality; this may act to decrease long-term viability.

Mountain Pine Beetles in the Black Hills - A Century of Science

FS News Posted on: August 17, 2016
A new scientific synthesis “Mountain Pine Beetles: A Century of Knowledge, Control Attempts, and Impacts Central to the Black Hills” from the U.S. Forest Service showcases findings from 100 years of research on mountain pine beetles in the Black Hills.

Long-distance dispersal of a subadult male cougar from South Dakota to Connecticut documented with DNA evidence

Publications Posted on: June 24, 2016
We report the long-distance dispersal of a subadult male cougar (Puma concolor) from South Dakota to Milford, Connecticut, where it was struck and killed by a vehicle. Genetic samples suggest this animal originated from the Black Hills of South Dakota while isotope analysis and physical inspection revealed no evidence that the animal had been held in captivity.
