Freshwater Habitat Protection Key To Poverty Alleviation

Group work at SBAG

Poverty alleviation and biodiversity conservation are inextricably linked in the Sekong Basin of Lao P.D.R., where freshwater fisheries are critical for ensuring food security and the economy. Here fish contributes 61 percent of the protein intake of these communities, and community health and livelihoods are being threatened by a loss of fisheries productivity and diversity due to increased regional demand for fish, forest products and electricity.

As part of the Indo-Burma Hotspot strategy, CEPF awarded the World Wildlife Fund for Nature (WWF) $200,000 to help protect the critical freshwater habitats of Lao P.D.R.’ Starting in June 2010 and ending this past May, the project aimed to demonstrate to policy makers the importance of healthy freshwater ecosystems to local communities in the Sekong Basin by fostering the development of community groups to protect freshwater habitats. Based on the Integrated River Basin Management (IRBM) approach, fisheries co-management was arranged between local communities and the government, which gave communities that use fisheries the authority to demarcate protected areas and enforce village regulations within them.

The project was successful in establishing communal fishing conservation areas in the Sekong Basin for 24 villages along 500 kilometers of riparian habitat. WWF worked with these communities to draft fish conservation zone management plans that gained endorsement from the Laos Department of Livestock and Fisheries (DLF) within the Ministry of Agriculture and Forestry (MAF).  Additionally, the biodiversity and ecosystem services values of the Sekong Basin were integrated into development planning, both at the local level in the fisheries and agriculture sectors, and at the national level in terms of hydropower planning.

Not only is the Sekong Basin important for human well-being, but the tributary also supports populations of at least 15 CEPF priority species, including Asian giant softshell turtles, Asiatic softshell turtle, giant freshwater stingrays, Jullien’s golden carp, green peafowl, white-winged duck, and Asian elephant. In addition to simply increasing the length of river under community protection, the project also enhanced connectivity between existing protected areas, thereby bringing conservation benefits to migratory fish species moving between management zones.

The positive impact on the local communities and fisheries was tremendous, as 75 percent of the communities reported that fish had increased in the fish conservation zones. According to Dr. Victor Cowling, landscape manager with WWF-Laos, “Communities consistently report increased availability of wild fish within one or two years of conservation zones being established. This aquatic resource conservation benefits peoples’ livelihoods and nutrition, with fishing becoming more rewarding for food and for sale.”

Group work at SBAGEven though the project end date has passed, the freshwater protected areas established continue to receive support from the DLF. At the community level, official recognition of communities’ traditional rights over their fishing area provides them with the enhanced power to exclude outsiders using destructive fishing practices. Over time the increase in fish and other aquatic products will help create strong incentives for these communities to continue engaging in freshwater habitat protection and biodiversity conservation.

Dr. Cowling noted that the fish conservation zone approach is already being replicated in a project funded by Oxfam Novib in three central provinces of Laos.  Additionally, the monitoring, evaluation, and fish catch monitoring methods partly developed during the Sekong project are being used in a new WWF project in Siphandrone, one of the three most important wetland sites on the lower Mekong.”

Fish Habitat Structures built for fish to live at Lake Julia

HERMITAGE — With the dredging of Lake Julia just about complete and the lake bed for the most part frozen, park personnel, consultants and volunteers took to the mud and muck Saturday building and placing fish habitat structures.

The structures, built at Buhl Farm park, Hermitage, will give fish a place to nest and lay eggs and escape their larger enemies, but also will help anglers know where to cast their lines.Dozens of unique habitat models at fishiding.com

Volunteers from Shenango River Watchers and Farrell Area High School; workers from dredging contractor Kirila Contractors Inc., Brookfield; park personnel; and agents of the Pennsylvania Fish and Boat Commission built and placed four kinds of structures out of rock and wood boards or posts – rock stars, spider humps, rock clusters and rock rubble humps.

While some of the structures are just piles of rocks or posts sunk into the lake bed, others are more elaborately constructed.

Spider humps are made of treated posts as a foundation, with hemlock posts secured to the treated posts, emanating outward like spider legs, and sandstone rocks piled on top.

Another kind, porcupine crib juniors – boxes built of hemlock boards arranged in the manner of Lincoln logs with gaps to allow the fish to enter – were assembled by fifth-graders from the Shenango Valley schools who participated in the last Outdoor Environmental Education Day at the park.

The structures with wood stimulate the natural food chain by giving  algae something to grow on. Invertebrates will feed on the algae and fish will eat the invertebrates, said Keith Beamer, lake habitat manager for the fish commission.

“It’s sort of like a coral reef out in the ocean,” said Jeff McDowell, who works for the maintenance department of the park.

The lake was drawn down last year to improve the dam outflow structures and officials decided to have the lake dredged while the water level was reduced to that of a stream.

The process killed all the fish that lived in the lake, but park officials and the fish commission came up with a plan to restock it with bluegill, crappie, bass and catfish. Officials plan to have local Boy Scouts and Cub Scouts help with the stocking.

Posts made of alkaline copper quaternary treated wood will stick out of the surface of the water, giving anglers a guide for casting.

“The fishermen like it because they know where the fish are more likely to be,” Beamer said.

Although the wood is treated, it is not supposed to harm the lake’s water quality or any of the creatures that live in the water, Beamer said.

The boards are made of hemlock, which are expected to have a 50-year underwater life.

The restocked fish will be fingerlings, but officials are talking about putting in trout to give anglers something to cast for this year.

Park officials are not in a hurry to refill the lake as ice on the structures could damage them, but believe it will fill quickly once the outflow is closed.

“Some places, it’s going to be 18, 20 feet deep,” said Thomas W. Kuster, park board member and trustee.

Kirila workers, who used heavy equipment to dig holes for the treated posts and move around the 15 tons of rock used to build the structures, stayed on after the structures were placed to smooth out the lake bed.

“They’ve really gone the extra mile,” Kuster said of Kirila workers. “They’ve taken pride in the project.”By Joe PinchotHerald Staff Writer
