UPCOMING Tree Cleaning Events

Join us to remove Paxtle from our native trees so that they may live long and strong.

Invite your friends, family and neighbors to join you.  With so many trees that need our community’s attention, we need to build an army!  We promise you will find this a valuable and rewarding experience.  

We have a supply of leather sleeves to protect your arms, heavy duty gloves and tools for cleaning.  If you have a good tree pruning saw and/or a ladder, please bring them! 


Saturday July 31   Tree cleaning clinic from 8:30 am -9:30 am.  Learn best ways to clean,  prune and care for trees with an expert!

Sunday, August 1   

HOURS8:30 am – 12:30 pm each day.

LOCATIONPeninsula near OTOMI (map)

Need transportation? Please let us know and we will arrange a ride-share.

Together we can save our native trees

Save our Trees is a program to conserve and protect our native trees located in public open spaces and local parks.  At Parque Landeta and “the Peninsula” (located near our boathouse at the Presa Allende), we have identified nearly 1500 trees requiring immediate attention.


If you have wanted to get involved in the community and love nature and the outdoors (and trees!), this is a perfect opportunity for you.  Together we can save our local trees and forest land by removing Paxtle and pruning damaged branches. Join in at any or all of our Save a Tree communty events, and bring your family and your friends! You will find this to be a very rewarding and enjoyable experience.

Help Save Trees and More through your Membership

Donate to our cause to save trees and preserve the nature of San Miguel through an annual Audubon membership contribution or make a monthly donation to help us sustain this program and the work of Audubon for years to come.

We need to purchase more tree-cleaning equipment and hire professionals to clean the tallest (and oldest) trees. Your membership contribution will also help to fund other valuable Audubon programs, including Niños y Naturaleza and Nature in the City.

Native trees need our help

Our native Mesquite and Huizaches are suffering from an epidemic of Paxtle (Tillandsia Recurvata), commonly known as la Plaga.

Paxtle, is a plant that survives on air, but uses trees (and other surfaces) as a structure to live upon.  In small quantities it is not harmful to trees, but right now thousands of native trees in San Miguel are covered with large colonies of Paxtle, which blocks the sunlight they need to produce food, leaves and seeds.  Eventually these trees will weaken, lose their ability to reproduce and ultimately die.

If this plague is not addressed, we stand to lose what remains of our urban forests and individual native trees throughout our community.

The time to act is now!

Trees are invaluable

It is not possible to overstate the value of a tree.

When they breathes out, it helps us breathe in. Their canopies shade us from the sun and provide sanctuary during rainstorms. Their roots hold soil in place and provide nutrients to the soil. Their leaves, fruit and seeds are a source of food and medicine for people and animals. Their strong branches support nests and roosts for animals on the hunt or needing a rest. Their different shapes, sizes, textures and vibrant colors contribute beauty to the landscape and you probably won’t be surprised to know that being around trees can actually chase our blues away.

What’s more, trees are one of our best natural defenses against climate change, desertification and the water scarcity challenges that are hurtling toward us.

For all of these reasons, and for the sake of the trees themselves, Audubon de Mexico is launching a community Save a Tree program.

The importance of our native trees

Our native are well adapted to long periods of drought and have developed uniquely beneficial relationships with our native fauna.  As members of the legume family, they add nitrogen to the soil which is an essential nutrient for the growth of all plant life.

Two months after it was cleaned and pruned, the tree was in full leaf.

Cleaning trees works!

To test the value and process of cleaning trees, in February 2021 we led a clean-up supported by thirty volunteers.  With an engaged, responsive volunteer crew, pruners and step-ladders we removed infestations of Paxtle in 30 trees in just one day. And what’s more, the results of this effort were impressive.  Returning to the site six weeks later, we discovered that the cleaned trees, which in February were lacking leaves, had fully burst into leaf. 

Tree Inventory

In June, 2021 Audubon board members worked with two groups of youth volunteers with San Miguelense Chingon to inventory trees at Parque Landeta.  We tagged and counted the trees heavily infested Paxtle in a section of the park and used Google Maps to estimate the total number of trees at risk within the entire park.  As many as 1400 trees are at risk,  right now.

Parque Landeta - 1400 trees at risk from Paxtle

The Peninsula - 600 trees at risk from Paxtle
