Global Warming: An Urgent Challenge, a Weak Response

Curbing the devastating effects of global warming is the most urgent challenge of our time. A new government report, out last month, reveals how climate change is occurring far faster than most models predicted. As detailed in the report (available at: http://www.globalchange.gov/publications/reports/scientific-assessments/us-impacts, serious effects on U.S. water resources, agriculture, sea levels, wildlife distributions, and human heath now appear to be unavoidable, and in many cases are already under way. The question is, can we avoid the worst-case scenarios?

In late June, the U.S. House of Representatives narrowly passed the American Clean Energy and Security Act, HR 2454, which at least begins to move our country in a positive direction and creates a path for our transition to a clean energy economy. The keystone of the bill is a market-based approach to reduce emissions, creating a cap or ceiling for carbon pollution and reducing that cap over time as emission goals are met. It requires major sources of carbon emissions to obtain a pollution permit called an “allowance”for each ton of carbon dioxide or equivalent they emit. These allowances will create revenue that can be invested in clean energy, energy efficiency, aid to consumers and wildlife and natural resource adaptation. In the intense bargaining leading up to the bill’s passage, however, its sponsors agreed to give away 85% of the emission permits for free in the first years of the program, seriously undercutting their effectiveness.

Unfortunately, this was only one of many ways in which key provisions of the bill were severely weakened in the final negotiations. Others include watering down the renewable energy standard (from 25% in 2025 to 15% in 2020) and promising huge payouts to utilities, oil refineries, and agribusiness.

Nevertheless, President Obama, Al Gore, and most environmental groups, including National Audubon, hailed the House passage of the bill as an essential first attempt at grappling with the climate change crisis. It is hard to argue with that: certainly something is better than nothing. Still, it was dispiriting to see how resistant many, many politicians remain to taking any action whatsoever to address a crisis that threatens every ecological and economic system on Earth. Observing the spectacle, New York Times columnist (and Nobel laureate in economics) Paul Krugman could find only one description: “treason against the planet.” And, the legislation still must pass the Senate, where it is expected to meet even more resistance. The question for all of us is: how can we get our political leaders to treat climate change with the seriousness and urgency that this crisis demands?

Some Good News for Wildlife

On a more positive note, recent weeks have brought several favorable decisions for endangered wildlife:

Oregon Gains First Marine Reserves

Finally, in another piece of good news, the Oregon legislature approved a bill in June that implements the recommendations of the Governor’s Ocean Policy Advisory Council (OPAC). The bill establishes two pilot marine reserve projects at Otter Rock near Depoe Bay and Redfish Rocks near Port Orford. It also outlines a procedure for the planning of Oregon’s new marine reserves, including the development of regional community groups that will assist with the shaping of four potential marine reserve sites: Cape Falcon north of Manzanita, Cascade Head north of Lincoln City, Cape Perpetua south of Yachats and Cape Arago-Seven Devils south of Coos Bay.

”With this historic vote, Oregon is taking new action to preserve, monitor and research Oregon’s vital ocean resources,” said Susan Allen, director of the Our Ocean coalition. “We look forward to working with Oregon’s foremost marine experts and the community to shape an ocean policy grounded in the best available science.”

Passage of a marine reserves bill was a top priority for the Oregon Audubon Council this year, and Rogue Valley Audubon was actively involved in efforts of pass this legislation. So, give yourselves a pat on the back!

Murrelets in the News - and It’s All Bad

This past month (Feb. 07), two major scientific reports were released concerning the Marbled Murrelet. This robin-sized seabird nests in the canopy of coastal ancient forests from central California to Alaska, and is listed as a threatened species in the lower 48. Populations of murrelets in California, Oregon, and Washington have crashed in recent decades, in large part because of loss of nesting habitat due to logging. However, the species is far more numerous in British Columbia and Alaska, and this fact was used as the basis of a lawsuit by the timber industry to force the Marbled Murrelet off the Endangered Species list.

In response to the lawsuit, the Bush administration ordered a review of the Marbled Murrelet’s status throughout its range. The results are now in, and, as was the case in a recent review of the population status of the Spotted Owl (also conducted due to timber industry pressure), the data show that the Marbled Murrelet is in even worse shape than we thought.

The first comprehensive look at population surveys in Alaska and British Columbia found an overall decline of about 70 percent over the past 25 years, dropping the estimated population to 270,000 birds in Alaska and 54,000 to 92,000 birds in British Columbia. In other words, the "stronghold"of the species is not looking secure at all. The author of the review, federal seabird biologist John Piatt, stated that none of the known human-caused threats to Marbled Murrelets, including oil spills, gill nets, and loss of nesting habitat to logging, appeared adequate to explain the drastic and widespread declines, particularly in Alaska. It is possible that changes in ocean conditions, perhaps related to climate change or to overfishing, may be responsible.

In the other study, researchers at U.C. Berkeley estimated rates of murrelet reproduction and survival by documenting the ratios of birds in different age groups using museum specimens collected between 1892 and 1922. They compared these results with values predicted from comparison with other bird species, and with contemporary rates obtained from murrelets captured at sea and from mark-recapture studies.

Based upon the study, the researchers estimate that 100 years ago, there were nearly 30 juvenile Marbled Murrelets - those less than a year old - for every 100 adults in the central California population they studied between Half Moon Bay and Santa Cruz, a ratio that was nearly identical to that predicted from comparative analysis. Today, there are only three to four juveniles for every 100 adults.

At the historic rate of reproduction, a marbled murrelet population would have experienced a stable to healthy growth rate of 2 percent per year. The authors note that murrelets only lay one egg each year, so the population, even when healthy, likely never grew very quickly. The modern-day reproduction rate indicates a population declining at a rate of 7 to 9 percent per year. This change in reproduction levels suggests limitations in nesting habitat and food availability, and increased predation on eggs and chicks by jays and ravens, according to the study’s authors.

"Our results suggest the marbled murrelet will need all the protection it can get - both on land and at sea - to recover healthy rates of reproduction," said lead scientist Dr. Steve Beissinger. "Unfortunately, the U.S. Fish and Wildlife Service recently proposed to greatly reduce the area of old growth forest designated for protection as critical habitat for this bird and has not protected near-shore habitats at sea, where the murrelet spends most of its life."

Information about Jackson County Land Use

Kathleen Donham
January 2007

In 1973 the state of Oregon passed historic land use legislation, Senate Bill 100, and promptly scheduled a long series of public meetings throughout the state to discuss this growth management program. This unique land-use planning legislation, with guidance from citizen input, identified nineteen statewide planning goals to be administered through the Land Conservation and Development Commission [LCDC] to oversee progress toward those goals. [See goals at: www.lcd.state.or.us/LCD/goals.shtml.]

Despite challenges to the Oregon land use laws like Measure 37, the land use program still functions in the planning departments of each county. Measure 37, a ballot initiative passed in 2004, allows properties owned prior to passage of land use law to an exemption from development restrictions. Measure 37 claims from local property owners are filed with the Jackson County Planning Dept. and hearings eventually come before the County Commissioners with no public input.

Here in Jackson County, the Planning Commission and the Jackson County commissioners write county comprehensive plans with citizen input. These plans require urban growth boundaries [UGB’s]. As the cities in the Rogue Valley have grown, these UBG’s have grown, threatening agricultural land and open space. Since Oregon land use goals aim to avoid those threats, the Rogue Valley Council of Governments is coordinating a multi-city planning effort called Regional Problem Solving [RPS] with the intention of a regional, cooperative planning process that will conform to the requirements of state law.

The Regional Problem Solving process has been ambitious, and must deliberate slowly in order to answer many questions of committee members. Some in the county are impatient with the process. The RPS meetings include a technical team of professional planners and specialists, and the full committee includes mayors of Medford, Jacksonville, Phoenix, Talent, Ashland, Central Point, Jackson County planners, and up until recently, County Commissioner Dave Gilmour. Commissioners Jack Walker (up for re-election along with Dave Gilmour) and Commissioner C.W. Smith have requested that they be included in the process rather than allowing Gilmour to represent the county. The public is welcome to attend; meetings are announced on the Jackson County web page.

In the midst of this process, the Jackson County Commissioners recently approved a new designation of land within the county called Rural Use [RU]. In addition to the standard categories of land outside UGB’s, i.e. Rural Residential, Exclusive Farm Use, Forest Reserve, this new category establishes parcels which could be developed as residential or commercial properties. The county planners had recommended that these parcels be restricted to no less than 20 acres, but two of the three commissioners (Smith and Walker) voted to reduce the restriction to 10 acres. The local land use group Friends of Jackson County has appealed this action.

How will these developments affect wildlife, particularly avian habitat, in our area? Development usually reduces wildlife habitat. It is especially noticeable in riparian areas. As wetlands are drained, resource land is given over to non-native species, and tree removal exposes soil to erosion, Audubon members may note changes in the assemblages of birds and a major decrease in nesting areas.

Birders interested in land use issues can help stem the tide of overdevelopment by attending land use hearings, reporting development which appears to be in conflict with good land stewardship, and supporting advocacy groups or persons involved in land conservation projects. Commissioner Smith has stated that enforcement of county ordinances related to land use will improve with designation of new county enforcement officers. He believes that the new RU designation will provide an alternative to Measure 37 claims. RVAS recommends close attention to the land use decisions.

 

Smokey, Stumps and CO2:
Finding the True Causes of the West’s Fire Problem


by Pepper Trail

By now we’ve all heard - oh, how often have we heard! - that a century of fire suppression has created a buildup of fuels that threatens an inferno across the forests of the West. Forest Service officials, once happy to pose for photos with Smokey Bear, now give grim news conferences to announce that natural fire regimes are terribly unbalanced, and that only massive "fuels reduction" can retrieve "forest health." Under the business model promoted by the Bush Administration, such fuels reduction projects are generally paid for by cutting trees large enough to be profitable for the timber industry.

To many, that seems like a reasonable tradeoff in order to fire-proof our forests for the long term. But before we embrace this vision of logging our forests back to health, let’s examine its basic assumption. Is unnatural fuel buildup really causing increased fire severity?

Like all seductive oversimplifications, the idea that fire suppression has created a tinderbox in the West’s public forests has elements of truth. It’s true that federal fire-fighters have been extraordinarily successful at keeping fire out of most western forests for decades. It’s true that fuel loads are high in many places as a result, particularly in ponderosa pine forests that evolved with frequent surface fires. Most obviously, it’s true that fire cannot be kept off the land forever: sooner or later, flammable fuels will burn.

But there’s a problem. According to the fire suppression hypothesis, the longer since the last fire, the more fuel buildup, and the worse the next fire. A simple, clear relationship - simple, clear, and wrong. A meticulous new study in the Klamath Mountains of northern California has shown that, when fire does come, forests that have not burned for a long time actually burn with lower intensity than more recently burned forests. What’s more, tree plantations experienced twice as much high-intensity fire as did multi-aged forests. That’s right: young stands, whether created by logging or by stand-replacement fires, are more flammable than forests full of big old trees. This really shouldn’t come as a surprise: when you’re getting a campfire going, do you toss on some kindling, or a two-foot thick log?

This research shows the folly of logging big trees to reduce fire risk. In many forests, such an approach is likely to increase fire severity. The study also points out an obvious but too-often overlooked reason for our current fire problem: past logging activities. Over the last hundred years, our biggest impact on the forests of the West has not been fire suppression. It has been the elimination of over 80% of old-growth by logging. What remains are younger stands with smaller trees and more brush - exactly the sort of forests that are the most flammable.

There’s another problem with blaming increasing fire severity on fire suppression. Any experienced firefighter will tell you that both the behavior of individual wildfires and the severity of fire seasons are driven by one factor above all: weather. Large-scale atmospheric patterns that bring low rainfall and high temperatures are far more important in producing major fire years than is the biomass of fuel present, which varies little on an annual basis. There has been an increase in severe weather events over recent decades, which many experts believe is a consequence of human-caused global warming. If this is the case, the bad fire seasons of the past ten years may pale in comparison to what is coming. And what is our government doing to address carbon dioxide emissions or even acknowledge global warming? In a word, nothing.

It’s time to stop pretending that there is a simple "cure" for the many and varied problems of our diverse Western forests. What is needed is first, a cautious and site-specific approach to forest management; and second, a clear focus on actions that will protect human life and property. There’s no question that wildfire is a serious threat to many rural communities, which are often surrounded by logged-over forests. To deal with that threat, fuel reduction should be carried out in the immediate vicinity of those communities. Away from the interface, federal forest managers need to focus on thinning the regenerating plantations and small polewood stands that are the true forest tinderboxes.

Together, Smokey Bear and public lands loggers have created the conditions that global warming could turn into the perfect firestorm. But if we respond calmly and thoughtfully, we can do much to reduce the risk to our communities, without logging one big tree from our last remaining old forests.

Oregon Land-Use Issues Update


by Kathleen Donham

Oregon enacted Senate Bill 100 in 1973 establishing the Land Conservation and Development Commission (LCDC) which developed statewide land use planning goals after obtaining substantial public input. Since that time, the state population has grown, and many people new to the area are confused by the ordinances and restrictions placed on building and development in Oregon. Ballot Measure 7, approved by voters in 2000, aimed to compensate property owners for economic losses associated with the Oregon planning process.

On October 4, 2002 the Oregon Supreme Court ruled on the constitutionality of Measure 7. The Oregon Department of Land Conservation and Development gives this report of the court’s findings: "unanimously concurred with the Marion County Circuit court’s decision that Ballot Measure 7 was unconstitutional and therefore invalid in its entirety". The Supreme Court ruled that Measure 7 made two or more amendments to the Oregon Constitution that were not closely related, denying Oregonians a chance to vote on each amendment separately.

Meanwhile, in an effort to pass legislation which would address the perceived concerns of the public regarding "takings", the Oregon House (HB3998) attempted to resolve questions about how to compensate landowners for losses of property values. No agreement was reached during this 2001-2002 session.

Land-use conflicts will continue to be political issues in Oregon, but the current economic downturn has made the prospect of huge payouts to landowners by municipalities seem even more remote.The fall 2002 election contained ballot measures designed to change the make-up of the state judiciary to include those more sympathetic to property rights constituencies, although at this time, neither of those (21& 22) appear to have passed.
