Forests constitute a valuable natural resource, especially when including non-timber forest products (NTFPs). Bioprospecting for and sustainable exploration of native species and the development of protocols for seedling production promote conservation. Piper aduncum L. stands out in several regions of Brazil because of several biological activities, notably action as a repellent, antimicrobial and insecticide. This study aimed to evaluate the influence of defoliation and different substrates on the cutting process. For this, an experiment was conducted in February, 2016 at the Health Plant Department, Sector of Agricultural Sciences, Federal University of Paraná (UFPR). Piper aduncum stem cuttings with 10 cm and 1/3 of the leaf area and defoliated cuttings. Stem cuttings were washed in running water for 5 minutes for subsequent use in three different substrates (medium sand sifted, vermiculite and commercial substrate Tropstrato HP®). The experiment design was completely randomized in a 2×3 factorial arrangement (cutting type x substrate), and it was evaluated the rooting percentage, mortality, shoot emission, number of roots and average length of the three largest roots after 60 days. The results confirmed that the presence of leaves in P. aduncum stem cuttings promotes adventitious rooting. The different substrates did not exert a significant influence on the performance of the cuttings in this species.

Piper cernuum Vell., a native species known as pariparoba, presents essential oil with potential properties and significant growth in clearings, being indicated for the recovery of degraded areas. Prospecting studies for new botanical matrices need the development of specific essays of plant propagation for future domestication of the species. This work aimed to evaluate the rooting of different types of cuttings using different substrates to develop a seedling production protocol. Stem cuttings with one or two nodes were installed on three types of substrates (medium sifted sand, vermiculite of medium granulometry and commercial substrate [Tropstrato HP®]) and maintained in greenhouse for 60 days to evaluation of the percentages of survival, mortality, sprouts, rooting, average number and average length of the roots. The results showed interaction between cutting types and substrates for rooting percentage and sprouting cuttings. The largest rooting percentages were observed in apical cuttings planted in sand and vermiculite (57.0 and 55.25%, respectively). Cuttings with two nodes presented higher performance than those with one node when compared for the analyzed variables.

Native Piper species present significant repellent, antimicrobial, inseticidal, anti-tumor and anti-protozoal biological activities. Studies on new species can discover unpublished potentialities and vegetative propagation for the development of cultivation protocols and reduce the natural extraction. The objective of this study was to evaluate the rooting of P. arboreum, P. cernuum and P. diospyrifolium stem cuttings with different treatments containing doses of indole butyric acid (0, 500; 1,000; 1,500; 2,000 and 3,000 mg L-1). Branches were collected in the “Bom Jesus Biological Reserve”, Parana state, Brazil. The cuttings, with a length of 12 cm and average diameter of 6 mm, were placed in 53 cm3 plastic tubes with the commercial substrate Tropstrato HP® and intermittent misting. After 90 days, the survival, mortality, cuttings with new shoots, number and length of the three main roots were evaluated. The percentages of rooting reached an average of 67.5% for P. arboreum, 51.6% for P. cernuum and 50.4% for P. diospyrifolium. A positive effect in the treatments containing the plant regulator was observed for rooting development, percentage of cuttings with shoots and number of roots per propagule, but there were variations in the responses of each species. Leaf retention was an important factor for the adventitious rooting formation in all evaluated species.

Protected Areas (PAs) are created for the protection and maintenance of biological diversity, but many of Ghana’s PAs are subjectto severe pressures and threats, the main pressures being the illegal extraction of natural resources. Rattans are indisputablyone of the most important Non-Timber Forest Products (NTFPs) in Ghana’s Protected Areas that is without doubt one of thereasons for which it has drawn the attention of researchers. In this study the illegal rattan extraction patterns in the AnkasaConservation Area (ACA) in Ghana was inspected. Simple random sampling and Snowball sampling techniques were used. Datacollection employed the use of semi-structured questionnaires, interviews and field enumeration of rattans as well as an analysisof Effective Patrol Man-days (EPMDS) from 2004 to 2012. The results showed a significant positive correlation (r = 0.75, p<0.05, r2 = 0.557) between patrol effort and rattan extraction encounters. In addition, there was a general reduction in illegalrattan extraction encounters from 2004 to 2012 at a rate of 4.3 per year. The highest illegal rattan extraction incidences wererecorded in 2006 (76 encounters), 2005 (35 encounters), 2008 (22 encounters), 2004 (18 encounters) and the least incidencewere recorded in both 2010 (3 encounters) and 2011 (3 encounters).The research also revealed that Eremospatha macrocarpawas the most extracted rattan species followed by Laccosperma secundiflorum. The major rattan extraction and trade routesoriginate in the northern parts and in the area east of the reserve and also south of Draw River Forest Reserve. Generally, rattanpoaching in Ankasa Conservation Area has declined, but there are still human incursions in the northern part of the reserve. Thestudy recommended an intensification of patrols in the north of the reserve. Also, enrichment planting and Agroforestry practicesof inter-cropping rattans with seasonal crops should be pursued vigorously for the local communities.

This study sought to: (1) identify the types and sources of Non-Timber Forest Products (NTFPs) traded; (2) find the frequencyof the NTFPs trade and (3) identify the challenges in NTFPs trading in the Sunyani Municipality. The survey was carried outfrom February, 2014 to April, 2014 mainly at the Sunyani Central and Nana Bosoma Markets in the Sunyani Municipality. Thetarget population comprised NTFPs collectors (gatherers), sellers and consumers. Respondents were purposively sampled. Atotal of 100 respondents were engaged in this study. The NTFPs were grouped into six categories namely; food, medicine,building materials, packaging materials, artefacts and domestic utensils. Key informants’ interviews were also conducted atthe Sunyani Forest Services Division to triangulate the data already gathered. Statistical Package for Social Sciences was usedto analyze the data obtained. The study demonstrated that domestic utensils (37%), food (33%), medicinal products (12%),packaging materials (9%), artefacts (6%) and building materials (3%) were the types of NTFPs traded in the two market centers.The results also showed that majority of the respondents (77%) harvest their NTFPs from forest lands as against 23% whoharvest from communal lands. A significant proportion of the respondents (52%) traded in above 40 kg of NTFPs and only 4%were seen trading in 10 kg of NTFPs. The study further highlighted that food (28%) and domestic utensils (26%) were regularlybrought to the market centers on weekly basis whilst significant proportions of medicinal products (9%), building materials(3%) and artefacts (4%) were brought to the market venues on monthly basis. Cumbersome permit procedure (40%), increasedmarket demand (15%) and financial constraints (20%) were identified as some of the challenges encountered in NTFPs tradingin the Sunyani Municipality. To ensure strict monitoring and sustainability of the resource, there is the need for sensitizationprogramme on the importance of NTFPs in rural livelihood and why their conservation is vital in meeting the needs of thepresent generation whilst not undermining their potential in supplying the needs of future generations.

The Canadian forest industries are based on the extensive harvesting and management of forests, with attendant effects on biodiversity at all levels of organization. In large part, conflicts between forestry and biodiversity occur because lands that are harvested and managed are mostly natural and seminatural ecosystems. Prior to being affected by forestry, such lands provided habitat for native species of wild life and their communities. Some of these elements of biodiversity may not find silvicultural habitats, especially plantations, to be suitable to their needs. In addition, the longer term integrity of some natural ecosystems, for example old-growth forests, is not compatible with any but the softest types of exploitation and management. This report discusses interactions of forestry and biodiversity at three levels of organization: (i) genetic variation within populations and species; (ii) the richness of species within communities; and (iii) the richness of community types on the landscape. A broader conclusion of our report is the following: If forestry systems of harvesting and management are to be practised in an ecologically sustainable fashion, then all elements of biodiversity must be accommodated within a landscape comprised of an integration of working lands and ecological reserves. The spatial scale of this integration could be various, ranging from large watersheds, to the "woodsheds" of particular industrial facilities, to provincial and national areas. Therefore, resolution of the substantial conflicts between biodiversity and forestry requires the design of ecologically sustainable landscapes that can provide a flow of timber and other valuated forest products, while still sustaining natural biodiversity resources.Key words: forest management, biodiversity, ecological reserves, eastern Canada, harvesting practices, old growth.
