Developments in Agroforestry Research
Agroforestry is considered as the basic approach to provision of food and alternative livelihood for upland farmers in the light of global competition.Through the years, various agencies and institutions have conducted researches/studies on agroforestry and have developed technologies and socioeconomic programs for upland development.This volume presents an integrated agenda on agroforestry.Specifically, it contains agroforestry outputs and highlights, as well as, policies, strategies and technologies deemed to address basic issues of poverty, resource use and equity, livelihood, ecological restoration, and the improvement of upland dwellers’ general welfare.  

Propagation of Some Indigenous Reforestation Species, Volume II
The present state of the country’s forest resources is indeed alarming.Millions of open and denuded forestlands need immediate rehabilitation and revegetation.With the excessive pressure on the remaining forest resources, the natural means of regeneration is definitely not sufficient to replenish these resources.It has to be largely supplemented by artificial means or by plantation establishment.This publication focuses on the seed and nursery technologies generated for a number of lesser-used indigenous reforestation species.The also include topics on seed collection, extraction and handling, storage, germination, potting techniques, cultural treatments, and prevention and control of pests and diseases.

Pests and Diseases of Forest Plantation Trees in the Philippines
The success of the government’s reforestation program depends on sustained efforts to grow our forests.To ensure the optimum growth of trees, young plantations must be protected against natural and man-made damages.An important factor in the survival of young trees is the prevention and control of pests and diseases attacking the different species, thus, this guidebook was packaged to give a comprehensive description of pests and diseases attacking seeds, seedlings, and trees.It also contains flowchart keys, host range, geographical distribution, life cycle or development and some suggested control measures for some very common and important forest pests.Likewise, different control tactics and the concept of integrated pest management (IPM) are briefly discussed.

Conservation of Biological Diversity in the Philippines
The Philippines harbors in its tropical territory, a remarkably high level of biodiversity and endemic species.Its natural resources and rich wilderness abound in genetic materials, varied species, and types of ecosystems that support and make up a wealth of biodiversity.However, through the years, the unabated destruction of our natural resources wrought by an ever-increasing utilitarian population posed a threat to the country’s biological and economic life support.This publication documents in one volume strategic conservation policies and directions that are adaptable in the country and presents the counterpart global stand on the issue of conservation taking into account its economic and legal implications to all nations.

Beginner’s Sourcebook on Philippine Rattan
As a forest crop, rattan remains as a promising resource of the country.The government look at rattan growing as a tool for rehabilitating our marginal areas.Since it will take a minimum of ten years for a rattan plantation to become economically harvestable, and rattan needs shrubs and trees to climb on, rattan has the potential to cover barren mountains with vegetation.This manual consolidates in one volume the information on rattan growing, harvesting, processing, and manufacturing techniques.The discussion also touches upon the dollar-generating possible of the species which need to be explored to the fullest. 

Improved Reforestation Technologies in the Philippines
This publication contains packaged practical and adaptable technologies on reforestation. The information is based on forestry research advances generated by government research institutes, as well as relevant experiences of the private sector. PCARRD publishes this volume with the support of the Department of Environment and Natural Resources (DENR) to cater to the information needs of all concerned in the national effort to regenerate the country's forest. 

Establishment and Utilization of Cover Crops in Reforestation Areas
In reforestation, planting of trees alone cannot prevent serious soil erosion.There is a need for additional vegetation growing under and between trees to adequately protect the soil.This publication discusses the advantage of planting cover crops before and during the planting operation to improve the soil quality and arrest the problem of erosion as well.It also provides reforestation contractors and managers the information on the advantage of covercropping as an appropriate soil conservation measure that also fits in with overall plans for combining production of food, forage, and other useful commodities, simultaneously with tree planting.

Rattan-How-to Series

The Rattan-How-To Series consists of three volumes:
      a. Seed Technology and Nursery Techniques
      b. Plantation Establishment, Maintenance, and Harvesting
      c. Chemical Treatment, Drying, and Seasoning of Rattan Poles

Mangrove Productivity
The conversion of the country's forests for economic activities has heavily drained the resource. These areas were transformed into agricultural land, fishpond, salt pond, etc. Such conversion eradicates trees and shrubs, denies some wildlife of their habitat, and even dislocates the coastal families who are dependent o the mangrove resource for livelihood. This publication is a documentation that resolves the most significant issue of maintaining our mangrove ecosystem at a sustainable level.

Environmental Research and Development
PCARRD’s effort to draw together in an in-depth consultative huddle the country’s environmentalists strengthens PCARRD’s intention to provide assistance, direction and central coordination for the nation’s environmental R&D activities.This is a result of a symposium on Environmental Research and Development that tackles the strategies for the protection and conservation of our different ecosystems working towards the making of a wholesome environment.This publication, likewise, discusses the state of the art of the environment and problems and issues attendant to the operationalization of the environmental research and development program.

Profile of Selected Non-Timber Forest Products
Forest denudation has long been a perennial problem in our country.Concomittant to this has been the dwindling timber and non-timber forest resources.This publication highlights the economic values and potential uses of these species and presents their botanical features, distribution, and habitat descriptions.The commercial utilization of these forest species is emphasized in this volume with the presentation of available technologies for their processing and product development.

Agroforestry in Perspective
Most of man’s needs is derived from the land, a resource fast becoming threatened by the onslaught of an expanding population in search for food and fuel.Pollution, erosion, siltation, forest denudation, squatting, droughts and floods must be checked to preserve the environment from undue degradation.And to all these challenges, the research sector is duty-bound to respond.This publication is a result of the Agroforestry Symposium-Workshop to place agroforestry in perspective as we harnessed the involvement of authorities in the field from the public and the private sectors.PCARRD believes that this is just one logical step towards a concrete natural resources research program.

Symposium on the Production of Lesser-Used Species and Small-Diameter Sized Timber
The lesser-used and small-sized timber species left standing in our logged-over areas may well be considered the last frontier of the Philippine forest.Years of unregulated logging have resulted in the dwindling of our virgin forest, the main source of our timber supply.This has prompted PCARRD to gather all concerned sectors into a symposium to determine the status of our lesser-used and small-diameter sized species and formulate strategies for their conservation and wide utilization.This publication is a result of this proceeding to help the policy makers, academicians, forest development officers, researchers, and the private sectors in the perpetuation of our forest resources.

Parks and Wildlife Research and Development in the Philippines:Current Status and a Mandatefor Tomorrow
The Philippines is endowed with beautiful parks and rich wildlife fauna.Unfortunately, these wildlife resources are beset with conservation and management problems.Researchers along this line have been fragmentary and neglected.PCARRD foresaw the need to gather all available information on parks and wildlife researches and come up with a comprehensive status report.This publication documents the Symposium-Workshop on Parks and Wildlife Research and Development in the Philippines: Current Status and a Mandate for Tomorrow.This publication is believed to identify gaps in all areas of concern and serve as basis for formulating future researches. 

Sylvan Power
We live today in a highly technological era when fossil energy is of utmost importance.This energy is needed for electricity, fuel and many other purposes.While the Philippines, to some extent, is an oil-producing country, the oil it produces is still insufficient to meet the country’s needs and demands.Sooner or later, this non-renewable commodity will be totally exhausted.To help alleviate this situation, PCARRD conducted the Seminar-Workshop on Forestry and the Energy Crisis and pooled the best scientific minds in the country to assess the stumbling blocks we face and propose the most plausible solutions.This publication documents the said workshop.

Proceedings of the Research and Development Workshop for Island Ecology Dynamics: Focus on Batanes
Batanes in its isolation, with its environmental stresses, and adaptation of its people has a lot to offer to outsiders who see it as another world; and to insiders who live in it as a matter-of-fact world of experience. This publication documents the issues/insights brought out during the workshop on Island Ecology Dynamics:Focus on Batanes.The first part discusses the unique environmental features of the island-province, the various man-made and naturally occurring stresses brought upon the province, and the need to come up with a comprehensive approach to provide solutions to all of these constraints among others.The second part provides the solid output of the workshop in terms of a package of R&D proposals which aim to address either separately or jointly, the technical and socio-economic aspects to a multidisciplinary approach attached to island-ecology related stresses.

Leucaena Research in Review
For the past years, induced by changing economic values, a better understanding of the forest resources of our country emerged.This brought about the identification of other products from the forest with economic and ecological importance.Among these is Leucaena.Because of its numerous uses and potentials, Leucaena has been the subject of research in the Philippines and even in other tropical areas like Hawaii, Australia, Taiwan and the Republic of China.This publication documents the results of the National In-House Review for Leucaena Research.The results of this undertaking explore how Leucaena technologies can be made applicable in the field and how the benefits from these generated technologies can be maximized.
