BiosphereRestoration.org
Our mission is to educate and empower the 8 billion people on the planet to restore ecosystems and watersheds in their nations and homelands to sequester carbon, reverse Global Warming and stop the current mass extinction.
BiosphereRestoration.org is expanding our efforts in multiple research, conservation and education directions to help increase our impact and reach. Please donate and support our work. Thank you.
BiosphereRestoration.org provides in depth research-based ecological methodologies to teach people how to restore natural forest ecosystems and use beaver dam analogs (small dams that fish can swim over or through) to restore streams and watersheds, hold back water on the landscape, and create wetland habitat for wildlife and people.
We believe restoring natural forest ecosystems and watersheds globally can reverse Global Warming and stop the current mass extinction. Our goal is to get every person on this planet to plant a tree and organize with your friends and neighbors to restore forests and streams and help repair our beautiful planet.
Beavers have been eradicated from many parts of North America, Europe, the Middle East and Asia. Beavers capability to sequester carbon and make Climate Refuges for threatened and endangered species, makes them one of the best tools our civilization can use to accelerate the repair of our biosphere.
The Global Loss of Wetlands
In the last 200 years, 85% of wetlands have disappeared (Crist, E., 2022).
Beavers Create Climate Refuges
"An estimated 80% of all terrestrial vertebrates rely on riparian ecosystems at some point in their lifecycle (Krueper 1993). Beavers reverse habitat loss by creating stable wetland and riparian ecosystems that are resistant to flood, drought, and fire. A wide variety of plants, insects, amphibians, fish, mammals, and birds live in beaver ponds. Beavers are considered a keystone species, as well as ecosystem engineers (Fairfax and Westbrook, 2024)."
Beavers Reduce the Effects of Drought
"Beaver dams slow the flow of water, reducing peak flows downstream (Puttock, Graham, Cunliffe, Elliott, & Brazier, 2017), storing and gently releasing water in times of drought (Hood & Bayley, 2008).
Small beaver dam analogs, made a natural materials found along the stream bank, can be used to restore streams and reverse damage from deforestation and herding.
Impacts of Deforestation and Herding on Streams
For centuries, deforestation and herding along streams have severely denuded stream vegetation and reduced the build up of forest-derived organic matter such as leaves, twigs, branches, and logs in stream channels. The reduction of organic matter and structure in stream channel reduces resistance and the ability of the stream to slow down, hold back and store water. This results in the lowering of surficial aquifers and the drying out of surrounding ecosystems.
Beaver Dam analogs
Beaver Dam Analogs or BDAs are small artificial dams (that fish can swim over or through), typically made of natural materials found along the stream, that trap sediment, hold back and slow down water, and help restore the stream bed's elevation to its natural level. The use of BDAs, in combination with forest restoration, should increase the duration of streamflow in all seasons, create habitat for upland, aquatic, and wetland species, create a more humid climate, reduce water stress in times of annual and prolonged drought, and reduce sediment loads. BDAs are an excellent tool to help restore stream ecosystems before reintroducing Beavers.
Beaver Dam Analog Maintenance
Beaver Dam Analogs are relatively simple structures. They span the width of the stream and help hold back and slow down water. When they are built small and/or leaky (In Australia BDAs are called leaky weirs), impacts to the stream bank are reduced. Because BDAs do connect with the bank and effect erosional processes, installed BDAs need to be periodically monitored and repaired to prevent and minimize stream bank erosion.
BiosphereRestoration.org is focused on applying permaculture and ecological engineering approaches to hold back water on the land and create wetland ecosystems.
Reshaping Nature and Restoring Ecosystems
In the last century, Ecologists started applying Engineering and Systems principles and approaches to restore natural ecosystems and create systems that benefit society such as wastewater treatment wetlands, for example. In the 1960s, the fields of Ecological Engineering and Permaculture arose out this movement.
Permaculture
Permaculture is an ecology and systems-based land management approach that engineers and alters natural systems to maximize ecosystem services. Permaculture was invented by Bill Mollison and David Homgren. It is an amazing approach, widely used by farmers, ranchers, gardeners and land owners, that can restore ecosystems and sequester carbon.
Ecological Engineering
Ecological engineering is defined as “the design of sustainable ecosystems that integrate human society with its natural environment for the benefit of both." Ecological Engineering was invented by Howard T. Odum. "It involves the restoration of ecosystems that have been substantially disturbed by human activities such as environmental pollution or land disturbance; and the development of new sustainable ecosystems that have both human and ecological value (Mitsch and Jorgensen, 2003)."
"Forty percent of the global population lacks access to clean, safe drinking water (Díaz et al., 2019).” Watershed restoration using small beaver dam analogs can not only sequester carbon but also provide clean water for drinking.

"Global forest area is now approximately 68 per cent of the estimated pre-industrial level (Díaz et al., 2019).” BiosphereRestoration.org is dedicated to teaching people how to collect seeds, grow forest species, repair broken ecological processes, and restore climax forest ecosystems.
The Earth Currently has over 3 trillion trees
The Earth has over 3 trillion trees. "Of these trees, approximately 1.39 trillion exist in tropical and subtropical forests, 0.61 trillion in temperate regions, and 0.74 trillion in boreal regions (Crowther et al., 2015)." Crowder et al., 2015 estimates "that over 15 billion trees are cut down each year, and the global number of trees has fallen by approximately 46% since the start of human civilization."
Together, We need to Restore almost a Billion hectares of Climax Forest
"The restoration of trees remains among the most effective strategies for climate change mitigation. We mapped the global potential tree coverage to show that 4.4 billion hectares of canopy cover could exist under the current climate. Excluding existing trees and agricultural and urban areas, we found that there is room for an extra 0.9 billion hectares of canopy cover, which could store 205 gigatonnes of carbon in areas that would naturally support woodlands and forests (Bastin et al., 2019)."
Forests Sequester half of all Fossil Fuels Emissions
Pan et al., 2024 "found that the carbon sink in global forests was steady, at 3.6 ± 0.4 Pg C yr−1 in the 1990s and 2000s, and 3.5 ± 0.4 Pg C yr−1 in the 2010s. Carbon sinks have increased in temperate (+30 ± 5%) and tropical regrowth (+29 ± 8%) forests owing to increases in forest area, but they decreased in boreal (−36 ± 6%) and tropical intact (−31 ± 7%) forests. The global forest sink is equivalent to almost half of fossil-fuel emissions (7.8 ± 0.4 Pg C yr−1 in 1990–2019). However, two-thirds of the benefit from the sink has been negated by tropical deforestation (2.2 ± 0.5 Pg C yr−1 in 1990–2019). To protect the forest carbon sinks, we need to limit deforestation, promote forest restoration and improve timber-harvesting practices (Pan et al., 2024)."

Blue Carbon Ecosystems sequester large amounts of carbon in plant material and soils. They have been severely impacted by nutrient loading (eutrophication) of coastal waters. The restoration of watersheds globally will help remove nutrients from stream waters allowing for the restoration of Blue Carbon Ecosystems.
Mangrove Forests
Mangrove forests sequester between 4 to 20 Pg of blue carbon (i.e., 4 to 20 billion tons of carbon). Donato et al., 2011 estimated mangrove forests sequester about 1023 Mg of carbon per hectare with about 159 Mg of this being located above ground. Donato et al., 2011 also found that mangrove forests store between 71-98% of their carbon below ground in estuaries and 49-90% below ground in oceanic areas.
Kelp Forests
Kelp forests and macroalgae consists of both tropical and temperate species that include red, brown, green and blue-green algae. Worldwide, macroalgae sequesters approximately 173 teragrams of carbon per year (or about 381 billion pounds of carbon per year/ Krause-Jensen and Duarte, 2016).
Seagrass Meadows
Worldwide, seagrasses sequester 75.5 to 151 Tg of carbon in biomass and up to 19.9 Pg of carbon in seagrass soils. 19.9 Pg of sequestered carbon is roughly equal to what is stored globally in tidal marshes and mangrove forests combined (Fourqurean et al., 2012).
Stopping Mass Extinction
“We are living in the time of the Sixth Mass Extinction. While many details elude us, we know that a mass extinction is underway from comparisons between background and current extinction rates, precipitous drops in wildlife populations, the shrinking of wild places, and the critical endangerment of biodiverse ecologies such as grasslands, tropical forests, wetlands, rivers and lakes, coral reefs, and continental shelves (Crist, E., 2022).”
“An estimated one million species are currently at risk of extinction (IPBES 2019) and current extinction rates are calculated to be several orders of magnitude greater than background rates estimated from the fossil record (De Vos et al. 2015) (UNEP Global Environment Outlook 7, 2025).”
In 2024, the World Wildlife Fund’s Living Planet Report 2024—A System in Peril, found that 73% of wildlife around the world have disappeared between 1970 and 2020.
BiosphereRestoration.org mission is to restore forests globally to sequester carbon and create high quality forest ecosystems.
The Speed of Deforestation
"Between 1990 and 2015 logging reduced native forest cover by 290 million hectares (for comparison, the US state of Texas is about 70 million hectares). (Crist, E., 2022)".
Degree of Forest Loss
High-biodiversity tropical forests continue to dwindle, and global forest area is now approximately 68 per cent of the estimated pre-industrial level (Díaz et al., 2019).”
Global Loss of Mangrove Forests
Globally, over half of the mangrove forests have been lost due to urban development, aquaculture, mining and overexploitation for timber, fish, crustaceans and shellfish (Giri et al., 2011/Duke et al., 2007/Alongi, D.M., 2002).
A large percent of our planet is degraded due to deforestation, herding, and poor agricultural and land management practices. Restoring these degraded areas can sequester carbon and stop the current mass extinction.
Land Degradation
"Seventy-five percent of land surface has been altered by human activity (Crist, E., 2022)."

Agricultural and Pastoral Lands
"Over one third of the world’s land surface and nearly three-quarters of available freshwater resources are devoted to crop or livestock production (see UNEP's Figure 4.2 below). Crop production occurs on some 12 per cent of total ice-free land. Grazing occurs on about 25 per cent of total ice-free lands and approximately 70 per cent of drylands (Díaz et al., 2019).”
