Drought and bark beetles are causing significant tree death in the New Mexico Forestry Division's Socorro District, which includes Grant County. Long-term drought has weakened trees, making them more vulnerable to bark beetle infestations that have reached epidemic levels due to the lack of moisture. Residents are advised to take preventative measures like year-round watering to help strengthen their trees' defenses against the dual threats.

Why it matters

The tree die-off in the Gila ecosystem is a concerning example of the cascading impacts of climate change, as prolonged drought and insect outbreaks devastate the region's forests. The loss of trees not only impacts the local environment and wildlife, but also threatens the livelihoods of residents who rely on the forests for recreation, resources, and their community's character.

The details

According to the New Mexico Forestry Division's Socorro District Office, the tree mortality is being driven by a combination of long-term drought that has weakened trees, and acute winter drought that has left them undefended against native bark beetle infestations. The bark beetles, normally present at low 'endemic' levels, have now reached epidemic proportions and are attacking even healthy trees.

  • This winter marked the second consecutive year of acute winter drought, also known as 'snow drought', in the region.
  • The tree die-off has been ongoing in the greater Gila ecosystem, which includes Grant County.

What they’re saying

“Native bark beetles — always present across the landscape at some level, usually 'endemic' vs. epidemic level — encountered undefended hosts, reproduced and, in some cases, then attacked/overwhelmed 'healthy' hosts.”

— New Mexico Forestry Division, Socorro District Office

“I kind of explain it as an immune system. We're building up the immune system and the reserves of those trees to be able to handle the drought that's coming in the summer.”

What’s next

The Grant County Extension Office is encouraging residents to closely monitor their trees for signs of decline, such as die-off, lack of leaf growth, or other indicators of stress. The office can provide guidance on watering techniques and facilitate sending tree samples to the New Mexico State University lab for analysis.

The takeaway

The tree die-off in the Gila region is a troubling example of how climate change-driven drought and insect infestations can devastate local ecosystems. By taking proactive steps to support the health of their trees, residents can help mitigate the impacts on their community and environment.
