Cheetah Conservation in Namibia


Since we visited the Cheetah Conservation Fund (CCF) near Otjiwarongo, Namibia, in 2008, there have been many achievements of conservation interest and two in particular that caught my eye:

1. Cheetahs have been successfully reintroduced to an area of southern Namibia where they had long been absent, and

2. A "Bush Project" is up and running. The Bush Project is described thus on the CCF Web site (http://www.cheetah.org/?nd=ccf_bush_project):

“The purpose of the Bush Project is to create a viable market for biomass products derived in environmentally and socially appropriate means. This will encourage the removal of excess bush from Namibian farmlands. Depending on the results of this pilot project, habitat restoration efforts could be vastly scaled up to restore cheetah habitat on an ecologically appropriate scale.”

This is the place where Hannah and I took a large box of derelict but good cameras and other optics and electronics as a donation from members of the Association of Professional Biologists of British Columbia. CCF uses the cameras as camera traps for cheetah research.

The whole country around Otjiwarongo and much of northern Namibia is covered with thorn-scrub brush, apparently not a natural situation that resulted from farmers putting out fires over many decades. CCF developed technology to cut up the brush and compact it into firewood. Since the brush is always growing, it is a never-ending supply. Local people can operate it and it gives them a business. It improves the land for wildlife (we saw 7 species of antelopes there!), and for livestock. More antelopes means more cheetahs. Also, since cheetahs hunt by pursuit on flat grassland, it is not just the forage for antelopes (hence, prey for cheetahs), but the cleared land itself that helps cheetahs hunt. So it is win-win-win-win situation.

Namibia is the only country in the world with a healthy, wild, and expanding cheetah population outside of nature reserves, and that is mainly due to the work of Dr. Laurie Marker and her Cheetah Conservation Fund. Her groups works with ranchers and farmers to make their properties “cheetah friendly,” mainly with respect to design and location of fences, but also in not poisoning or otherwise killing cheetahs. When farmers, game wardens or others capture cheetahs alive, they bring them into CCF for rehabilitation and eventual release. Also, a lot of ranches are also game farms (but they call them wildlife reserves) that offer guided hunts. So Namibia is also one of the few countries that allows hunting of cheetahs, because it has a healthy population and the ranchers are involved in their conservation. That makes it a win-win-win-win-win situation.

Plus, the CCF is temporary home to a revolving-door of wildlife researchers who are investigating ecology of not just cheetahs, but also brown hyenas and many other species. So it is a win-win-win-win-win-win situaiton.

Conservationists Need Bear Hunters



With the spring bear hunt come articles in the newspapers and radio talk shows on the probity of killing bears. Environmentalists don’t like it. Hunters like it and they are supported by guides, outfitters, the Guide Outfitters Association, and the provincial government. What the hunters know and the conservationists don’t is that they are on the same side of a losing battle over conservation of wild lands and wildlife.

Meanwhile, as Larry Pynn (The Vancouver Sun, April 3) pointed out, the government raised the overnight fee for a camp site up to $30 per night. Add on reservation fees and buy a bundle of firewood and you are looking at $120 for three nights of camping. Does anyone not see how these are related?

Pynn quotes Environment Minister Barry Penner conceding that just 2.48 million people used BC Parks campgrounds in 2009, compared with 2.89 million in 1998, a 14% decline for the decade. Most people visiting our parks don’t even stay the night: overnight use has declined to about one-tenth of day use.

Not just here, but in the United States, Europe, and Japan, per capita visits to national parks, number of fishing and game hunting licenses, and time spent hiking or backpacking have all declined since about 1987. This worries resources management agencies because outdoor recreationists are their political constituency. Without public demand for wild land, natural scenery, wildlife viewing opportunities, and, yes, hunting and fishing opportunities, there will be no political will to protect them.

The trend is the same in Alberta. For example, although absolute numbers of visitors to Banff National Park tripled to four million (not counting those who simply drove through to other destinations) between 1970 and 2004, the number of people using the backcountry declined from a peak of 20,300 user nights annually in 1975 to 18,000 annually by 2004. Jasper National Park shows a similar trend.

A 2006 survey showed that, relative to the average Canadian pleasure traveller, visitors to British Columbia are especially likely to participate in nature-oriented activities (e.g., camping, canoeing and kayaking, horseback riding) but less likely to go fishing or hunting; and 53% of Canadian travellers to British Columbia stayed in a public campground. Tourists may stop at a casino while they are in British Columbia, but that is not what they come for. They come for nature, in all of its forms and products.

Through their license fees, hunters and sports fishers pay far more for habitat conservation than do most environmentalists as individuals. Their other expenditures are important to the economy, but are unevenly distributed throughout the province. In 2001, 18% (395 businesses) of all nature-based businesses in British Columbia operated in Northern BC (encompassing Prince George and Prince Rupert to the Yukon, Alaska and Alberta borders), but 47% (111) of guide-outfitters operated in this region. Guide-outfitters in the region generated $136.5 million in revenues in 2001.
The number of resident hunting licences in British Columbia peaked at 174,000 in 1981 and has declined ever since. The decline is not only in the number of hunters, but in the numbers of game that they take. Thus, the large-game harvest fell 27% after 1981, though most of the downturn occurred in the 1990s. Between 1992 and 2002, the resident harvest of big game species fell by 40%. The harvest of deer and moose fell sharply after 1992, by 47% and 13% respectively. The bighorn sheep and mountain goat harvest fell by 34%. Because of lower hunting pressure and healthy game populations, hunters have been expending fewer hunter-days per kill for deer, elk, moose, and caribou. These statistics haven’t escaped the notice of non-resident hunters, whose take has increased by more than 20% since 1992.The grizzly hunt, subject to ever-tighter wildlife management restrictions, fell 41% in the same period. However, since 1976, non-resident hunters have taken an increasing proportion of the total grizzly bears killed by hunters.

One area that bucks (no pun intended!) the downward trend is in the hunter kill of cougar and wolves. These predators specialize on deer, elk, and moose. With prey populations expanding, both in response to habitat changes (logging, fires, and land-clearing for agriculture) and to the lowered hunting pressure, the wolves and cougar have plenty to eat. In 1986, wolves re-colonized Banff National Park after a 30-year absence. About the same time, after a quarter century of never hearing their howls or seeing their tracks around my cabin in the Kootenays, I heard a wolf howl. My son, living there now, has heard them howl, and soon my grandchildren will. It is my fervent hope that wolves, grizzly bears, and cougars will always remain a feature of these forests.

Personally, I loathe the idea of killing large predators. I killed a bear once and swore I never would again. As a biologist who has radio-tagged grizzly bears and tracked them to and from their den sites, frankly, I came to love bears. .. black, white, or brown. There is no biological justification for hunting bears. But neither is there any biological reason to disallow hunting, as long as the hunter take is in line with the annual production (this is an open question, but one for another time). Neither is it a moral issue—or, if it is, it is one where we city-dwellers need to consider the rights and values of country-dwellers here and guests from abroad. We live in British Columbia, which has as fair a chunk of mountain wilderness, unrivalled for scenic beauty and large mammal diversity, as almost anywhere else on Earth. Although some 2.3 million of us live in the Greater Vancouver area, the other 1.6 million live in towns, villages and a handful of small cities scattered across the province. Many are First Nations trappers, ranchers and others who hunt for meat under aboriginal entitlements and, yes, who guide hunters for extra income in the fall. Many are business people who own outfits (a Crown land tenure for commercial hunting), sporting goods stores, cafes or motels that cater to resident and non-resident hunters. With nature-based recreation decreasing, and with the government discouraging the public from camping by setting exorbitant fees, we conservationists need all the friends we can get. Hunters are among them.

Another piece of the Atlantic Rainforest falls



Someone forwarded to me a video about Ford Motor Co.'s new, modern manufacturing plant in Brazil with a comment about globalization and what it means for American workers, but what caught my eys was the statement: “...amid the remnants of the Atlantic Rainforest...”. This is one of the world’s top 25 “biodiversity hotspots,” one of the most biodiverse ecosystems and most endangered and it’s just about gone. It hosts a huge number of species that occur nowhere else, including several monkey species. I have photo of two species, the Golden-headed Tamarin shown above, and others posted at http://picasaweb.google.ca/Lee.Coquitlam/Primates# that I took in the Lisbon Zoo. By 2003 the Atlantic Forest was down to about 5% of its original area (around 70,000 km2) and shrinking fast. It has (or had) 261 species of mammals, 73 of which occur no where else in the world. Species are still being discovered there, but it seems that it is being destroyed so fast that many of its species will be lost before they are ever “discovered” by scientists—although the local people who eat them know that they are there! I guess when they are gone, we can thank Ford for their small part in this environmental catastrophe.


I’ve never been there. Maybe I will one day, but I'd better hurry or it will be gone.

Globalization is bad, not just because it engenders poverty in the already-poor while enriching the already-rich. What it means for the environment is that as long as any country has resources left, another country will buy them, in many cases from the politicians and their friends, leaving their own people without productive land and resources. The economies of the rich countries can run as long as there are resources somewhere that they can buy, but every year fewer countries have resources left for sale, or for domestic use. The politicians haven’t noticed that the global economy has transitioned from one of producing countries competing for buyers for their resources, to consuming countries competing for access to dwindling resources. Meanwhile, the countries with no more resources for sale or local use often become “failed states” and a strategic threat to the interests of countries like the USA and Canada. It can’t last forever.
