Mission Statement

Tree New Mexico is dedicated to helping communities plant and care for trees in urban areas — large and small — throughout The Land of Enchantment.

Welcome to Tree New Mexico

Organizational History and Goal

For over 30 years Tree New Mexico (TNM) has been planting trees in the Land of Enchantment and educating the public on the value and necessity of healthy urban forests. We continue to be the premier private, non-profit tree planting organization in NM (and the nation); planting thousands of trees each year and building a high level of understanding and advocacy for the expansion and maintenance of urban forests.

Tree New Mexico was initially formed out of concern for the environment by local high school students on the premise that tree planting is an important and worthwhile national and community goal. Since our founding in 1990, our partners and volunteers have helped plant over 1,250,000 trees in communities throughout New Mexico. Founding Director, Sue Probart, ran TNM for the better part of 30 years. She was generally known in NM as “Ms. Tree” and was an instigator of urban forestry initiatives throughout the state.


Our Objectives:

  • Increase the canopy of urban and community forests throughout New Mexico.
  • Build public awareness regarding trees and the environmental role they play in our communities and the nation.
  • Provide environmental tree-based education for citizens of all ages.
  • Mitigate and reverse urban heat island effect in urban areas of the state.
  • Serve as an urban and community forestry advocate.
  • Build strong and effective partnerships with all levels of public and private organizations.
