Prairie ASMR to calm the nervous system

#FieldPhotoFriday traveling to other places and @nature.org wonders this Friday! Such cool research being done here in the tall grass prairie to determine the impacts of various uses, grazing, fire - oh my! 🌻🌾🪾🐂🦬🔥

Dendrochronology has impact across disciplines and all scales! Excited about how we're working at TNC AZ to incorporate more tree-ring studies into our portfolio

Field day Friday sights and sounds to calm the nervous system #SEArizona #SkyIslands #snowmelt

Back in 2021, I was trying to make "SUP" dendro a thing for us wetland/coastal investigators. We hypothesize this pond was created by a fault scarp ~200 years ago, drowning the cedars, and changing the landscape of Bainbridge Island, WA! doi.org/10.1130/B383... #DendroDating #TreeHistory

We're hiring a post-doc! I encourage anyone with interest in conservation/applied science and southwestern US ecology/hydrology to apply! Come think about important migration corridors with us ! 🐦⛰️🐆

A chilly, early morning re-entry into field work after maternity leave. Ramsey canyon is gorgeous and our monitoring has been collecting data for months! #desertWater #riparian #waterResources

A climate scientist appropriate nursery theme for baby #2 : *rain*clouds 🌧️Thankful for generous and supportive colleagues at @nature.org Thanks to @marcos-d-robles.bsky.social & @gardenlisa.bsky.social (who made this incredible rain- themed baby blanket!) for making the day special!

Managing our dry ponderosa pine forests in AZ from high density (left pic) to a🔥safe and💧resources friendly state (right pic- across the road) takes time, creativity, $$$, and perseverance! Our TNC team is doing incredible work near flagstaff to help our 🌲thrive! @nature.org @science.nature.org

This is the first time this restoration technique has been used in the southwest (piloted in the northwest) and in just 8 months we’ve seen the fen go from bare ground to a rich wetland ecosystem. Incredible work @usfs.bsky.social ! #Peat #Restoration #GroundwaterWetland

Yesterday I had the opportunity to tour the mega restoration project at AZ’s only “working” fen. Peat has been generated here for ~3000 years! The restoration strategy is “stage zero” - bringing the landscape to a level grade and letting the water do the work! #conservation @science.nature.org

@science.nature.org in AZ updated our webpages to better illustrate our work and impacts! Check out some of the things we've been up to to better prepare our communities and ecosystems for climate change and assess conservation impacts! ❄️🌲💧🌇

#troubleshootingThursday what are the best ways to detect tiny arid streams? We’re trying Satellites, cameras, temperature loggers, human observation…. #waterConservation

The same river, same day, 4 km apart. #SouthwesterRivers #AZwater #DissapearingWater #RiparianDeath #WaterConservation @science.nature.org

With little to no winter rains or floods- lots of baby fish this year!

Happy Fish Friday from our annual Patagonia Sonoita Creek fish survey! Sonoita creek is the happy home of 3+ native fish species that thrive in the varied habitat of Sonoita Creek #FieldPhotoFriday #Females4Fish @nature.org @science.nature.org

Another glorious day chasing water in the desert 😍 #FreshWater #Conservation #Science @science.nature.org

Got to climb trees today with some awesome ladies of the International society of Arborculture! Getting some urban tree practice in before we install instruments in riparian 🌳 of southern AZ this spring! #SafteyFirst #TreeClimbing #EasierWithoutChainsaw #Riparian

Today ☺️ #FieldPhotoFriday #Springtime #Riparian #FieldSiteScoping

Beautiful (and toxic) Copper Creek. This area has been a mining region for decades, and renewed interest in copper has led to continued exploratory drilling today. #conservation #engagement #impairedWaters

Take your boss to work day :) #GetOutside #NatureTherapy #Conservation @nature.org

another glorious installment of my #WhereAZWater field work

In Southeastern Arizona, this is often water that fell from the sky 20,000+ years ago and entered the ground water system!

Spent a lovely February day hiking through @nature.org Aravaipa Canyon to collect water from warm springs (>26•C). In Arizona, warm water often means OLD water! I’m looking to better understand this incredible system and magical place #hydrology #conservation #desertCanyon

Frosty trees and bluebird skies today as we toured some of @nature.org projects and lands in the upper San Pedro River valley. These recharge projects are helping sustain flows in the river and reduce flood damage across the landscape

Another glorious day in southeastern AZ: at the @nature.org Canelo Hills preserve we are gathering baseline water and ecology data before a controlled 🔥this winter. We’re working on better subsurface moisture measurements to determine the water impacts of this management. #conservationScience

@nature.org ‘s Middle San Pedro River preserve is an active research site where we try to understand the value of conservation practices on a retired agriculture field through space for time approaches. This preserve contains perennial water, old growth bosques, and many critters!

Ah, the gold of San Pedro River Cienegas in autumn 😍. Explored today to ponder what restoration might look like & what is the desired state, and identify challenges to enhancing this wetland for ecosystem. 🍂🌟 @nature.org #restoration #riparian #connectivity #freshwaterResilience

Very interesting indeed! There is some wonderful work diving into the details of why we don’t see more landslide activity from the 1700 quake. LaHusen, 2020 for example. This region is set up geologically for catastrophic failures, but triggers can be more complex, dependent on “priming”

can I get added?!

A nice shout out to my PhD work in New England - we worked to find statistical ways to tease apart temperature and moisture signals in coastal wetland trees to improve our climate reconstructions.
