Mountain Pine Beetle
The mountain pine beetle (Dendroctonus ponderosae) is a destructive bark beetle that attacks pine trees, especially ponderosa and lodgepole pine. It bores into the bark and introduces fungi that block water flow, causing needles to fade from green to red as the tree dies. Maintaining tree health and early preventative treatment are key to protecting valuable pines.


Ips Beetle
Ips beetles are a group of bark beetles that attack a variety of conifer species, with multiple species targeting different types of trees across the region. They primarily infest stressed or damaged trees, creating galleries beneath the bark that disrupt nutrient flow and can quickly lead to decline. Early detection and maintaining tree health are key to prevention.
Fir Engraver Beetle
The fir engraver beetle (Scolytus ventralis) is a bark beetle that attacks Douglas-fir, primarily targeting trees stressed by drought or damage. It creates galleries beneath the bark that disrupt water flow, leading to fading needles and eventual tree decline. Early detection and maintaining tree health are key to prevention.

Nelson Forestry Focus: Tree Health Care
We live in an area that creates many challenges for even the hardiest of trees.
Our dry Colorado climate can swing, sometimes very quickly, from moderate to extreme temperature--on both ends of the dial. Rain is inconsistent at best. The large percentage of rain and snow we get is often taken away by the sun, or wind. Add to this our soil, loaded with clay and rock. Soil Compaction is the norm. Your tree's root system daily struggles to find the nutrients and minerals needed to thrive.
Combine these factors, and it is no wonder that boring insects, leaf beetles, plant bugs and so many others contribute to the weakening and decline of trees that, anywhere else, would be beautiful and flourishing.
We have solutions to help your trees combat these issues.
