All nature lovers are familiar with thegreat profusion of mushrooms that popup in the forest as the fall season progresses. Somehow their ephemeralappearance suggests that they are not animportant part of the scene, and eventheir names suggest they are relatedrather to an unknown half-world ofgoblins and magic. Few people realizethat they have several essential rolesin the forest, performing jobs that noother living thing is equipped to do;and some people do not know accurately what a mushroom is or how itperforms its job.
What is a mushroom? It is merely thefruit of the "fungus plant" that produces "seeds" (spores) and then fadesaway. The "fungus plant" itself consists of an unseen network of microscopic threads (mycelium) that interpenetrates the habitat-soil, wood, duff,etc. Unlike the fruit that passes awayqu ickly, the mycel ium persists, oftenfor many years, doing its job and sending up its annual crop of mushrooms.

What are the jobs that the mushroomperforms? The most obvious work isin the area of recycling. Vast amountsof forest debris (fallen trees, branches,leaves, etc.) are continually being turnedback to the elements and cleared fromthe forest floor. Imagine, if you can, aforest in which no debris decays, building up year after year to make an almostinaccessible fire hazard, not to mentionthe lack of recycled minerals for continued growth of the trees. The groupof mushrooms responsible forerecycli.nghave the power to penetrate and breakdown lignin and cellulose by enzymaticaction.

The bonus of gastronomic value forhuman consumption is also beingrealized, as the Chanterelle and Pinemushrooms are gathered commercially.The casual collector is warned, however,that mushrooms are not to be taken forgranted and that, without accurateidentification, there could be "death inthe pot". •
In a few cases, mushrooms have turnedto a parasitic existence and cause rootrot and decay of living trees. The "Shoestring Mushroom" (Armillaria) is one ofthese, usually attacking weakened treesand then spreading out by means ofblack, stringlike rhizomorphs to neighboring trees.
Another group of mushrooms form apartnership with the roots of the livingtrees. This symbiotic relationship,known as mycorrhiza (= fungus root),is not obvious to the casual observer,but if roots are exposed, it can be seenthat the fungus has woven a mantleabout the roots. Through this mantleand its widespread network of mycelium, the fungus does the job of

CANADA-USA SIGN COOPERATIVE FORESTRY AGREEMENT
An umbrella agreement in the form of aMemorandum of Understanding on cooperation in the field of forestry wassigned in Washington recently byEnvironment Minister John Robertsand John R. Block, United StatesSecretary of Agriculture.
The purpose of the agreement is todocument and improve technical cooperation and coordination of forestryrelated programs undertaken in the twocountries, avoid duplication, and ensurecompatible data collection.
Mr. Roberts said much has beenaccomplished in the long history of cooperation in forestry between Canadaand the United States. The two countries have traditionally worked togetherin the area of forest protection, exchanging equipment and informationduring forest fire seasons and carryingout a joint research program on theSpruce Budworm.

"I am confident that the cooperative nature of our relationship with theUnited States in the field of forestrywill be enhanced through an agreementsuch as this one which provides formalchannels for carrying out work in areasof mutual interest between our twocountries", Mr. Roberts said.
The umbrella agreement allows theleading forestry agencies of the twocountries, the Canadian Forestry Serviceof Environment Canada and the UnitedStates Forest Service, to enter intosupplementary agreements on specificforestry activities.
Mountain Pine Beetle Agreement
A subsidiary agreement relating toresearch, development, and control programs for the mountain pine beetlewas signed six weeks after the umbrellaagreement.
The mountain pine beetle is currently the most damaging insect inwestern Canada, with infestations continuing to spread and intensify, mainlyin the lodgepole pine forests of BritishColumbia and Alberta. The total area ofheavy tree mortality has increased tomore than 230 000 ha. The volume oftimber killed over the past five years isestimated at almost 26 million cubicmetres, or nearly four times the annualharvest in Alberta.
The Canadian Forestry Service,using results from its continuing research program, is advising the provincial governments and other federaldepartments on methods for managingthis serious forest pest.
Realizing that movements of themountain pine beetle are not restrictedby international boundaries, Environment Canada has negotiated this agreement whose major objective is the

On September 2, 1982, EnvironmentMinister John Roberts announced theframework for a long-term, comprehensive program of forest revitalizationin Canada. The program reaffirms theneed for a concerted attack on forestrenewal in order to· meet the woodsupply goal of an increase in productionof at least 40% by the year 2000. Thistarget was adopted by the federalgovernment and the 10 provinces twoyears ago. The details of this policystatement have been published in an8-page bilingual brochure .

development of a common technologyfor more efficient management of thebeetle. The agreement, which is for afive-year period, will include cooperative work on management of beetleinfested or vulnerable stands and onpotential insect control methods.
The Pacific Forest Research Centre(PFRC) in Victoria will be responsiblefor carrying out the terms of the agreement in Canada. Various facets of theprogram will be carried out by PFRC'sresearch facilities, with the cooperationof the governments of B.C. and AI berta.Northern Forest Research Centre, Edmonton will be responsible for implementing some aspects of the agreement in their own area. In the UnitedStates, the states of Oregon, Washington,Idaho, and Montana are cooperatingwith the Pacific Northwest Station ofthe USDA Forest Service. In both countries, the university community is actingin a consulting and contractual role. •

development and relations group
~is being formed to undertake
I administration of the existingagreement and the recently im
\.,) A plemented forestry job creation-~ programs, as well as the plan-
ning and development of newagreements and improving communications and relations withforestry sector clients in theregion.
It is expected the new program will be fully oper
ational early in 1983, once staffing has been completed. •
The new forestry developmentand relations group will be headed by a senior manager reportingdirectly to the Regional Director,
Ross Macdonald, who will be supported by six newprofessional staff, as well as the existing forest economics and job creation project staff already onstrength (see organization chart on opposite page).An additional three positions are being added tothe Administration Section to provide the necessarysupport.
"We will be looking for candidates who have demonstrated their commitment to forest renewal and areeager to work in a dynamic program in cooperationwith colleagues in the provincial forest service,industry, and our own scientists to meet the challenges of ensuring the long-term viability of B.C.'sforests," said Mr. Macdonald.
Some of these positions will be filled by staff transferring from DR EE. However, Ross Macdonald statedhe expected most of the professional positions to befilled by foresters who will be coming into the PublicService from other sectors.
The agreement, which was signedin May 1979, called for $50million to be spent jointly byCanada and British Columbia onintensive forest managementover five years to supplementongoing programs in the province. Specifically, it wasdesigned to intensify the job-creating potential of theforest resource and increase the wood yield beyondthat secured by the Ministry of Forests' normal forestregeneration program.
As a means of strengthening the federal government'scommitment to a long-term, comprehensive programof forest revitalization, Environment Minister JohnRoberts, responsible for the Canadian Forestry Service, recently announced a new policy to be known asliThe Framework for Forest Renewal"*. This framework will form the basis for new development agreements and for broader responsibilities for the CanadianForestry Service in the region in relation to itsclients and to other federal departments. It reaffirmsthe need for a concerted attack on forest renewal inCanada in order to meet the wood supply goal of anincrease in production of at least 40% by the year2000-a target adopted by the federal governmentand the 10 provinces two years ago.
These new responsibilities have resulted in a strengthening of the Canadian Forestry Service at the regionallevel. At the Pacific Forest Research Centre, a forestry
On September 3, 1982, federalresponsibility for the Canada/British Columbia SubsidiaryAgreement on Intensive ForestManagement was officially transferred to the Canadian ForestryService from the Department ofRegional Economic Expansion(DREE).

Canadian Seed ExpertsAssist Thai Government
Dr. Slavoj Eis, an ecologist at the PacificForest Research Centre (PFRC), andMr. AI Hedlin, an entomologist whorecently retired from PF RC, are two offour Canadian forestry experts chosento assist in the establishment of a ForestTree Seed Centre in Thailand.
Because of the importance of tropicalhardwoods to the economies of Southeast Asian countries, Canada, lead bythe Canadian International Development Agency (CIDA), is assisting theAssociation of Southeast Asian Nations(ASEAN) in the establishment of thisCentre which will also benefit thecountries of Indonesia, Malaysia, thePhilippines, and Singapore.
Dr. Eis and Mr. Hedlin will be joinedby Dr. K. Helium, a silviculturist fromthe University of Alberta, Edmonton,and Dr. N. Dhir, a genetist with theAlberta Forest Service, Pine Ridge, onone-year assignments to assist in thedevelopment of this program at theresearch centre which is located in the

Sara Buri district approximately 100miles north of Bankok.
The purpose of the Centre will be toserve as a resource for training in foresttree seed and silviculture research. TheCanadians will also assist in the development of forest tree seed orchards inASEAN countries in order to provideadequate su pplies of qual ity seeds ofselected species used in afforestationand reforestation. They will also be responsible for strengthening ASEANtechnical competence in tree nurseryand forest plantation research anddevelopment through training programs.
Part of Canada's contribution to theCentre consists of the provision ofshort-term, practical training of ASEANforesters at various Canadian forestryestablishments in British Columbia,Alberta, Ontario, and New Brunswick.Fourteen of these foresters arrived inCanada in mid-August to commencethis training which consisted of 100hours of instruction, lectures, and
Under Dr. Edward's guidance, theyhave been gaining hundreds of hoursof hands-on work experience in a seedlaboratory. They are also assisting heand his technician, Doug Taylor, with aresearch project and will be able toapply this experience when they returnto work in their native countries.
