Foundation gifts boost Wisconsin conservation efforts

Foundation grants of $1,000 to dozens of community efforts in Wisconsin will boost prairie restoration and shoreline revitalization, wildlife festivals and eco celebrations.

The Natural Resources Foundation of Wisconsin in mid-November awarded $28,370 to 30 applicants through the C.D. Besadny Conservation Grant Program. Projects range from restoring rare and important landscapes to improving understanding of natural resources through mobile technology.

“Using $1,000 or less, each of these 30 grant recipients will help protect critical wildlife habitat, restore native landscapes, connect people to Wisconsin’s natural wonders, and implement many other projects that will have a lasting impact on our natural resources,” said Caitlin Williamson, the foundation’s program and development coordinator.

A sampling of the grant awards:

  • 1000 Islands Environmental Center for Eagle Days on the River in Kaukauna, Outagamie and Calumet counties.
  • City of Superior for International Migratory Bird Day Celebration in Superior and Douglas County.
  • Covenant Harbor for a nature center in Lake Geneva, Walworth County.
  • Driftless Area Land Conservancy for habitat improvement in Dodgeville, Iowa County.
  • Eagle School of Madison for biodiversity surveys in Fitchburg, Dane County.
  • Friends of High Cliff State Park for tree replacement in Sherwood, Calumet County.
  • Friends of Lapham Peak for invasive species removal in Delafield, Waukesha County.
  • Friends of the Bird Sanctuary for the Barrens Festival in Douglas County.
  • Kishwauketoe Nature Conservancy for Kishwauketoe prairie and savanna restoration in Williams Bay, Walworth County.
  • Madison Audubon Society for connecting students with nature in Madison, Dane County.
  • Neighborhood House of Milwaukee for nature center stewardship in Milwaukee County.
  • Northland College for assessing the wildlife on Madeline Island in Ashland County.
  • Upham Woods for shoreline restoration in Wisconsin Dells, Adams, Columbia, Juneau and Sauk counties.
  • UW Arboretum for habitat restoration of Faville Prairie State Natural Area in Madison.
  • Wisconsin Land+Water for Wisconsin Envirothon in Rosholt, Portage County.
  • Allen Centennial Gardens for an Education a la Cart program in Madison, Dane County.

The grants help organizations create new ways to promote conservation in changing times, said Sara Vega, of Allen Centennial Gardens, whose program is intended to teach lessons about pollinators.

Grant recipients must match the award dollar-for-dollar — either with funds or in-kind services. To date, the foundation has awarded more than $475,890.00 to more than 593 projects in every county in Wisconsin since its inception in 1990.

25 years later, Exxon Valdez spill effects linger

Before the Deepwater Horizon oil spill in 2010 in the Gulf of Mexico, there was the Exxon Valdez disaster in Alaska, at the time the largest oil spill in the U.S.

The 987-foot tanker, carrying 53 million gallons of crude, struck Bligh Reef at 12:04 a.m. on March 24, 1989. Within hours, it unleashed an estimated 10.8 million gallons of thick, toxic crude oil into the water. Storms and currents then smeared it over 1,300 miles of shoreline.

For a generation of people around the world, the spill was seared into their memories by images of fouled coastline in Prince William Sound, of sea otters, herring and birds soaked in oil, of workers painstakingly washing crude off the rugged beaches.

Twenty five years later, most of the species have recovered, said Robert Spies, a chief science adviser to governments on the oil spill restoration program from 1989 to 2002. But some wildlife, as well as the people who live in the region, are still struggling.

Here’s a look at what’s changed since the spill:

FISHERMAN

Bernie Culbertson was preparing to fish cod when the Exxon Valdez ran aground. With oil in the water, fishing came to a standstill and life for he and other fishermen drastically changed.

“The bottom fell out of the price of fish,” he said. Pink salmon that sold for 80 cents per pound fell to 8 cents per pound. Consumers turned to farm fish or tuna out of fear of tainted salmon. His boat caught 2.5 million pounds of pinks one season and lost money.

Culbertson turned to other fisheries, traveling as far as California. Fishing 12 months a year, his marriage failed. Friends couldn’t repay loans and lost boats or homes. Exxon compensation checks, minus what fishermen earned on spill work, arrived too late for many.

The fisheries today are not the same. “The shrimp are slowly, slowly coming back. The crab aren’t back. The herring aren’t back. The salmon are back in abundance,” he said.

INDUSTRY

At the time of the spill, complacency among government officials and the oil industry had set in after a dozen years of safe shipments, said Mark Swanson, director of the Prince William Sound Regional Citizens Advisory Council and a former Coast Guard officer.

When the tanker ran aground, for instance, spill response equipment was buried under snow. Alyeska Pipeline Service Co. in 1989 had 13 oil skimmers, five miles of boom and storage capacity for 220,000 gallons of spilled oil.

Now, Alyeska has 108 skimmers, 49 miles of boom and on-water storage capacity of almost 38 million gallons. North Slope oil must be transported in double-hull tankers, which must be escorted by two tugs. Radar monitors the vessel’s position as well as that of icebergs.

The company conducts two major spill drills are conducted each year. And nearly 400 local fishing boat owners are trained to deploy and maintain boom.

PACIFIC HERRING

After the spill, the population of herring crashed. It is now listed as “not recovering.” The silvery fish is a key species because it is eaten by salmon, seabirds and marine mammals from otters to whales. Four years after the spill, the estimated herring population based on modeling shrunk from 120 metric tons to less than 30 metric tons.

How that happened remains a question, said Scott Pegau, research program manager for the Oil Spill Recovery Institute in Cordova, Alaska.

Here’s what’s known: Adult herring feed on zooplankton, which crashed for three years after the spill. With less to eat, herring may have been more susceptible to disease normally fended off within a herring population.

Herring populations can stabilize at a low or high number, but something has prevented a rebound. Oil likely is no longer a factor, Pegau said.

SEA OTTERS

Responders estimated that as many as 3,000 sea otters died the first year. Hundreds more died in the years after of exposure to oil that persisted in sediment, where otters dig for clams.

Three factors could have had an impact on the otters’ ability to survive. Oiled fur loses insulating value. Otters ingest oil as they groom, and researchers years after the spill found blood chemistry evidence consistent with liver damage. Grooming takes time away from feeding.

“One of the lessons we can take from this is that the chronic effects of oil in the environment can persist for decades,” said Brenda Ballachey, who moved to Alaska a few months after the spill and spent the next summer dissecting sea otter carcasses collected from beaches and frozen.

The U.S. Geological Survey research biologist is the lead author of a federal study released last month that concludes that sea otters have finally returned to pre-spill numbers.

PIGEON GUILLEMOTS

The pigeon guillemot, which looks like a black pigeon with web feet, is one species that has not recovered. Numbers were declining before the spill. An estimated 2,000 to 6,000 guillemots, or 10 to 15 percent of the population in spill areas, died from acute oiling.

Researchers suspect river otters, mink and other predators targeted guillemot eggs as an alternative to foraging on oiled beaches.

Like sea otters and another bird that took years to recover, harlequin ducks, pigeon guillemot’s forage for invertebrates in sediment and likely were affected by lingering oil, said David Irons, a seabirds expert with the U.S. Fish and Wildlife Service.

The decline of its other prey, juvenile herring, didn’t help. Numbers continue to decline in both oiled and non-oiled areas. Irons has proposed reducing mink numbers on the heavily oiled Naked Islands, once prime habitat for guillemots, to restore their numbers.
