When we see land as a community to which we belong, we may begin to use it with love and respect. There is no other way for land to survive the impact of mechanized man, nor for us to reap from it the harvest it is capable.
– Aldo Leopold

The problem with beavers is that they think every stream and wetland should be natural, but people need a place too, and this sometimes invites conflict. Partnering with beaver means managing them to protect people, property, and infrastructure. Coexistence is key.
Mark is a member of the Beaver Institute Beaver Corps, trained and mentored by Mike Callahan in the installation of flow devices and other coexistence measures.
EcoMetrics is a small group of applied scientists united in the mission of improving ecological health for people and nature. Mark Beardsley has a master’s degree in ecology and bachelor’s degrees in chemistry and biology. Jessica Doran has a bachelor’s degree in biology and a master’s in wildlife and conservation biology. Mark and Jessica have been working together since the 1990s and formed EcoMetrics to apply our passion for natural science in restoration. Over the past 20 years, we’ve applied scientific methods to monitor dozens of projects in Colorado mountain headwaters, and we’ve seen what tends to work and what doesn’t. Dave Sutherland came to EcoMetrics after a full career at the forefront of geodetic surveying. In addition to being the smartest guy we’ve ever met, Dave brought the technical expertise that allowed us to up the scale of monitoring and assessment using sophisticated survey and mapping techniques, remote sensing, and drones.
We haven’t given up on nature. We think restoration should be an ecological healing process and a logical extension of environmental ethics. We believe that restoring healthy ecosystems by reviving natural processes is better than imposing designs and building habitat. Stabilized stream channels and enhanced habitat have their places in the modern world, but when it comes to resilience, sustainability, and ecosystem services, there is still no substitute for the real thing. We’ve been promoting the importance of ecological health, complexity, dynamicity, and biological drivers for a decade, and have recently been teaching courses on the stream evolution model, Stage-0 restoration, beaver restoration, and low-tech process-based restoration.
We believe that testing hypotheses with rigorous scientific data and constantly challenging our assumptions in an open collaborative community is the best way to advance knowledge and the practice of stream and wetland restoration. We are eager to share our experiences and learn from others, and we are constantly challenging ourselves and our peers to find the best ways of working with nature to accomplish stream restoration and management goals.
Our decades of experience studying Colorado headwaters streams has led us to the inescapable realization that riparian connectivity and beavers are profoundly important drivers of stream health and function. This is now our focus. We now work mostly with land trusts, watershed groups, and other conservation partnerships to promote process-based restoration, beaver expansion, and enlightened land stewardship to Colorado headwaters. We formed Riparian Reconnect in 2016 with our longtime friends and restoration partners at Colorado Open Lands, Dr. Brad Johnson and Scott Gillilan to upscale this work and study its effectiveness in the Colorado Rocky Mountains.

EcoMetrics calls on a network of trusted partners to fulfill our restoration and conservation mission
(Beardsley 2020) Part of the USU 2020 Low Tech Process-based restoration workshop, this presentation provides examples and evidence of he amazing ecological potential that natural riverscapes exhibit and how low tech process-based restoration works to restore them.
(Beardsley and Doran 2020 RRNW) We propose an operational definition of stream health. Approaching restoration as a healing process, rather than as a design and build engineering exercise, is more in line with ecological standards (Palmer et al 2005), process-based restoration (Beechie et al 2010) and biomic restoration (Johnson et al 2019).
(Beardsley with Karin Boyd 2019 RRNW) This talk is a fun allegory that explains the fall of the natural equilibrium paradigm and “natural” channel design in favor of a new paradigm that highlights stream health and natural processes over stability (static conditions) and forced equilibrium.
(Beardsley 2018 SCW) Prior to human disturbance, many of Colorado's small alluvial headwaters streams were naturally anastomosed wooded beaver streams or broad grassy wet meadows. Restoring natural Stage 0 streamscapes provides greater hydrological, ecological, and habitat benefits compared to stabilizing and enhancing entrenched Q2 channels as dictated by traditional natural channel design methods.
(Beardsley with Colin Thorne, Janine Castro, and Sue Niezgota 2019 SCW) Stage-0 restoration explained. This talk covers the use of light-touch methods and working with beaver to restore native Stage-0 conditions on small to medium-sized streams.
(Beardsley 2019 SCW) Natural value theory and Aldo Leopold's Land Ethic explain why both natural values and people values are important, how stream health and human benefits can be integrated in decisions, and why stream health matters across the spectrum for both people and nature.
(Beardsley with Joe Wheaton, Jeremy Maestas, Steve Bennet, Scott Shevardian, Jay Wilde 2019 Gunnison) The masters of Low-tech Process-based Restoration taught a workshop in Gunnison and Mark got to help. All the course materials are available using this link.
(Doran and Beardsley 2019 RMSRC) This talk provides evidence of the importance of beavers and other biological drivers of stream form and function and how we can work with biological drivers to restore Rocky Mountain headwaters streamscapes to their natural condition using process-based approaches.
(Sutherland 2019 RMSRC) Relative elevation maps are indispensable for assessing, monitoring, and planning restoration of streamscapes. In the right hands, drones and modern software enable the acquisition of precise and accurate data REM data for a fraction of what it used to cost.
(Doran 2019 SCW) Is the growing interest in complex streams and Stage-0 a fad or is it real? It’s real alright, and it is important. There are lots of reasons why this new paradigm of streamscape form and function is catching on.
(Beardsley 2019 Upper Arkansas Wetland FAC) This talk discusses the importance of beaver streams as part of a watershed’s natural infrastructure and how we use natural process-based methods to restore them.
(Beardsley 2019) Ongoing stream temperature monitoring and comparison to standards in Park County, CO.
(Beardsley 2019 Colorado Stream Mitigation Summit) This presentation goes over recent developments in stream science and restoration practice and challenges those developing federal compensatory stream mitigation protocol for Colorado to integrate them.
(Beardsley 2019 CPW Workshop) This presentation opened a CPW workshop that brought together leaders in the state’s stream science and restoration community to consider potential water issues.
(Beardsley 2019 Buena Vista Community)
A scientist’s look at small streams and wetlands, what makes them healthy, and why they are important.
(Beardsley 2018 RRNW) Today's dominance of entrenched single-thread channels with dry, disconnected riparian zones is at least partially due to widespread anthropogenic conversion from native beaver streams. We found that some Stage 1 streams become arrested in Stage 1 and may continue to lose function through a gradual process of straightening and widening. A restoration approach that reverses the causes of degradation (reestablishing native riparian shrubs, beavers, and a highly-connected anastomosed planform) provides much more benefit and greater sustainability compared to stabilizing and enhancing entrenched channels using traditional natural channel design (NCD) methods.
