Extended Drying of The Rio Grande Affects Bosque

The unprecedented drying of the Rio Grande has made this yr one of many hardest summers for the bosque.  

A few month in the past, my co-worker Tucker and I had been heading out to conduct routine monitoring at one among our habitat websites in Corrales, New Mexico simply north of Albuquerque. The situation is a spot the place Audubon has been delivering water to the Rio Grande by way of our environmental water leasing efforts since early June of this yr. Strolling into the river hall we shortly seen that the outfall related to our water supply was inexperienced and verdant, whereas close by areas had been brown and harassed This harassed space was large-scale and looking out terrible -the website didn’t appear like this two weeks prior when all was inexperienced. Alarm bells rang as I skilled flashbacks, recollecting the speedy lack of a cottonwood-willow riparian forest in southeastern Arizona at Leslie Canyon Nationwide Wildlife Refuge in the course of the early 2000’s drought.    

Over the subsequent few days, I captured drone imagery all through the Center Rio Grande of New Mexico and located that the best impacts had been primarily to the riparian forest by way of Albuquerque with some harassed timber additionally close to Los Lunas. This was shocking since throughout river drying occasions during the last decade, the timber have survived as a consequence of shallow groundwater resilience – the best affect of river drying in earlier years has been to the fish group. The extent and depth of drying this yr have been unprecedented and is a direct consequence of a altering local weather.  

My coronary heart sank as I previewed the preliminary drone pictures at residence within the consolation of my swamp cooler. Virtually all the youthful timber appeared brown or gray, and the older timber had been thin-green to gray. Sadly, cottonwood timber don’t bounce again from prolonged drying since they depend on saturated soils for survival.   

Since 2019, Audubon has delivered leased water again to the river for environmental functions in choose areas to reduce river drying and uplift native wetlands. This program is coordinated carefully with the Center Rio Grande Conservancy District and the US Bureau of Reclamation, in addition to a community of different companions with shared pursuits in a residing Rio Grande. 

I despatched a deck of drone pictures out to our community of companions on the Center Rio Grande with urgency and a plea for motion. To my reduction, this was met with a sea-swell of concern and alarm from all. As I write, motion is underfoot to mix water from the Albuquerque-Bernalillo County Water Utility Authority, the Center Rio Grande Conservancy District and Audubon for a launch of water into our parched Rio Grande. The hope is to water the riverbed for 4 days by way of Albuquerque, soak the aquifer, and supply an “irrigation” to our harassed and dying bosque forest. On the similar time, a strong monitoring program has been put in place to grasp groundwater response, the seepage price, traits of the watering, and the response of the timber themselves. This monitoring effort will present invaluable insights to water managers about how we might resolve issues of this nature sooner or later.  

The place this can be a story of climate despair, that is additionally a narrative of resilience and a cause for hope. This coordinated water supply is a feat and couldn’t have been accomplished with out an unimaginable community of caring companions, together with the Albuquerque Bernalillo County Water Utility Authority.  

This summer time has been the toughest of summers; many farmers in our valley haven’t seen floor water irrigation for greater than 120 days, our Rio Grande Pueblos are scraping by on meager irrigation releases and are available subsequent yr we might even see as much as a 50% die-back of our treasured Rio Grande bosque by way of Albuquerque. To be clear, the forest dieback we’re seeing is commensurate with a large-scale forest fireplace and would require important funds and energy to handle postmortem.  

This collective water motion will enhance the chances of timber which are presently on the brink, timber which are very important for wildlife habitat and the well-being of our metropolis. Our partnerships, our communities and our individuals level in direction of a greater future as all of us grapple with the drying of New Mexico.
