Partnership Background and Need

What is Redwoods Rising?

Redwoods Rising is a collaborative of California State Parks (CSP), the National Park Service (NPS), and Save the Redwoods League (League). Together, we will be implementing a landscape-scale restoration program to improve redwood forest health and conditions across 120,000 acres of public lands in Redwood National and State Parks (RNSP).

Initial conversations about Redwoods Rising began in 2016, and a Memorandum of Understanding (MOU) that officially formalized the collaborative between RNSP and the League was signed on April 28, 2018. Although these three organizations have worked together on past projectst, this is the first time that we have formalized our relationships in this way.

Why is Redwoods Rising important?
80,000 of RNSP’s 120,000 acres of redwood forests were once commercially logged.

Through Redwoods Rising we are integrating restoration disciplines and practices to improve the parks’ remaining old-growth redwood ecosystems and restore previously logged areas. By joining forces we can better support the tallest forests on Earth while restoring and renewing habitat for threatened and endangered species and improving the experience of those who visit these forests.

As the complexity and costs of restoration continue to increase, the need for this kind of coordinated and efficient project planning, execution, and funding is more and more critical. Scaling up and accelerating the pace of restoration activities across jurisdictional boundaries is also necessary if these fragmented ecosystems are to be resilient to the wide-ranging and harmful impacts of drought, disease, invasive species, and climate change.

As managers of these lands, RNSP has been working for decades to restore the redwood forests under their care. The greatest obstacles they have faced have been a lack of adequate staffing and funding. Agency budgets will never be able to meet the full need; however, Save the Redwoods League is perfectly positioned to help raise the support needed to significantly alleviate these obstacles.

Together, we can achieve far more than any of us could alone

Who else is involved?
In addition to the collaborating organizations listed above, Redwoods Rising is engaging with tribes and local stakeholder groups and community members through the planning phases of our projects as well as during project implementation.

What are the primary goals of Redwoods Rising?
By combining our resources and expertise, Redwoods Rising is promoting the development of healthier, more vibrant redwood forests reminiscent of the old-growth that once blanketed this region. Our aim is to re-connect existing old-growth redwood stands in RNSP and restore old-growth forest characteristics to previously logged areas that have been heavily impacted over the past 150 years.

For the first time ever, we are working together to:
1. Create a shared restoration strategy
2. Enhance capacity for larger and more frequent restoration projects
3. Develop dedicated and increased funding to support ecosystem restoration
4. Build and expand public support for restoring, protecting, and stewarding redwood ecosystems

Where is Redwoods Rising?
The focus of Redwoods Rising is in Redwood National and State Parks, but the collaborative’s long-term vision includes connecting coast redwood forests and corresponding ecosystems across the north coast of California.

Restoration Goals and Need

120,000 acres? Where do you start?
Our vision is to restore the over 70,000 acres of degraded redwood ecosystems in the Mill Creek and the Prairie Creek watersheds of RNSP, to remove or restore hundreds of miles of abandoned roads, and to continue to build overall capacity for greater collaboration and enhanced restoration of redwood ecosystems.

We are beginning by rehabilitating over 8,000 acres of previously logged forests in the Prairie Creek Watershed and over 25,000 acres in the Mill Creek Watershed.

What does Redwoods Rising hope to accomplish in the future?
Our (very) long-term goal is to restore forests of giant coast redwoods in all 120,000 acres of RNSP.

Why restore the forest?
RNSP is home to 45 percent of the remaining protected old-growth redwoods, including some of the tallest trees in the world. However, 80,000 of the 120,000 acres of RNSP’s redwood forests were logged before they became part of the parks. Large swaths of too-dense, young forests that have grown up in these areas surrounding the remaining primeval redwood stands.

Some of these second-growth forests have grown back on their own, but many are a result of re-seeding or planting by logging companies after they harvested the original old-growth redwoods—often with non-redwood species such as Douglas-fir. Trees in these reseeded areas in particular are unnaturally dense, with as many as 10 times the number of trees per acre as an old-growth forest. These thin trees are desperately competing for space, light, water, and nutrients, crowding each other as well as important understory vegetation. These forests are not healthy and do not provide anywhere near the ecological values of a mature redwood forest.

Furthermore, failing and inaccessible old logging roads thread through the landscape, accelerating the spread of invasive species and sending sediment into nearby streams, potentially threatening endangered coho salmon and steelhead trout. Existing culverts and stream crossings installed by the logging companies that have not been maintained are also vulnerable to failure.

The goal of Redwoods Rising is to help undo this damage to fast-track the development of healthy redwood forests.

What are you restoring?
Previously logged second-growth forests are our primary focus; however, Redwoods Rising is also restoring streams and other associated ecosystems that are a part of a healthy landscape.

Were all of the logged areas in RNSP totally clear-cut?
Although many areas were clear-cut, in some places there are still old-growth trees scattered here and there among second-growth forests. These trees are reservoirs of genetic information and biological richness that can help support forest recovery. They also provide habitat for species that depend on old-growth trees, even within otherwise young stands. These trees also benefit from restoration activities that reduce competition for resources and that allow them room to reproduce through seeds or resprouting. By improving conditions around these residual trees, we in turn enhance their protection and habitat quality as well.

What are the characteristics of old-growth redwoods and why are they important?
The giant redwood trees of an old-growth forest have intricate canopies that create habitat, store large amounts of carbon and maintain high levels of biodiversity. Some species, such as marbled murrelets and Humboldt martins require old-growth conditions to survive. Less than 5% of the historical range of these forests remains.

Some characteristics of old-growth forests include:
1. Big, old trees of varying height, girth, and age
2. Large snags, or standing dead trees that provide habitat for a wealth of wildlife
3. Large fallen trees on the forest floor that decompose slowly over many decades providing homes for many of the smallest dwellers of the forest: insects, spiders, centipedes, and salamanders as well as fungi
4. A multilayered and continuous canopy with spatial variability, where younger trees and understory plants find space in the gaps between larger trees
5. Trees with large branches and deep crowns

Won’t nature heal itself if given enough time?
Such significant damage was done to the landscape by logging—and the associated roads, culverts and stream crossings—that in many cases natural processes like hydrology, erosion, and plant regrowth no longer function the way they would need in order for the system to recover on its own in the foreseeable future. If left alone, these ecosystems would likely continue to deteriorate for a long time before they could even begin to recover—putting the plant and animal species that depend upon them at great risk.

Furthermore, fierce competition for light among second-growth trees has led to stands of tall, skinny trees of similar age that are vulnerable to being easily knocked down by wind, rain, or snow or infected by pests and disease. Where that occurs, many trees can be lost at once as they are all similarly vulnerable, setting decades of forest regrowth back to the starting point. In some cases, non-redwood tree species such as Douglas-fir and even exotic tree species were planted or aerially seeded following logging operations, further altering forest composition away from a healthy redwood ecosystem. The shade from these unnaturally dense stands of young trees has dramatically reduced the amount of important understory vegetation in these areas as well.

Are you also restoring streams where salmon live?
We are improving fish habitat by removing upslope sources of erosion and sediment such as abandoned logging roads, and more directly with placement of large wood in streams, planting and expanding of riparian stream buffers, and by removing and/or upgrading stream crossings including inadequate bridges and failing culverts.

Are there economic benefits from this work?
Collaboration increases cost savings, improves information collection and sharing, and creates labor and materials efficiencies. Redwoods Rising is also helping protect park resources and past investments through invasive species management, and Storm Patrol, which helps prevent old logging road and culvert collapse during the rainy season.

Local economic benefits from redwood forest restoration potentially include contracted services for restoration treatments, timber processing, and also from increased visitation to the parks. Several local firms and individuals have already been hired to support planning and restoration work. There are also numerous long-term benefits from the healthy forests, fisheries, and resilient ecosystems that Redwoods Rising is helping to create.

Climate Change

How does Redwoods Rising combat climate change?
One of the exciting and environmentally important aspects of accelerating the growth of massive redwoods is that these trees are climate change fighters.

Research proves that coast redwood forests can store at least three times more carbon above ground than any other forests on Earth. So, as we restore the redwood forests, we increase their ability to absorb more carbon, and because the trees are so resistant to rot, they hold onto their carbon for a very long time even after they die. This is an effective, natural form of carbon sequestration. You can learn about redwoods and carbon in a six-minute ranger video.

Furthermore, healthy redwood forests will be more resilient to the effects of climate change such as warmer temperatures, drought, and different fire patterns and frequencies.
