Hello and welcome to my BlueSky account! I am a geoscientist who is passionate about community resiliency to environmental hazards with a long-term and nature-focused perspective. You'll find me happiest in mud, dirt, forests, and streams.
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

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! ❄️🌲💧🌇
In Arizona, we rely on science to confront our biggest challenges—wildfires, droughts and biodiversity loss. To deliver fast, large-scale solutions that protect communities and nature, TNC pursues evidence-based strategies grounded in our research. Learn more at nature.org/scienceAZ.
Arizona Conservation Science
TNC's conservation science in AZ engages stakeholders and expertise in applied science and policy to develop new ideas and tools to help solve the most pressing challenges affecting people and nature.

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

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

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

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

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.
Veronique Greenwood covers dendrochronology, the importance of archives, and changing climate signals in the Boston Globe (featuring me, other LTRR scientists, and former student Dr. Jessie Pearl) www.bostonglobe.com/2024/11/11/o...
The rings inside trees are beginning to tell a different story - The Boston Globe
If you cut down a tree, you can read an environmental record. Now climate change is complicating the narrative.

Last week I attended @nature.org One Conservancy Science Gathering in CDMX. I left inspired by the breadth of work TNC scientists are pursuing across the Earth, and prompted by @katharinehayhoe.com to migrate to Bluesky! Looking forward to sharing more about conservation science making a difference!

To get a sense of some of the work I do, my most recent paper uses 'witness' and 'victim' trees of two large debris avalanches in Northern California to date the events to be coeval with San Andres and Cascadian Subduction earthquakes.
