The Presence of IUCN Red List Tree Species in Dependence of Site Characteristics in the Vietnamese Cat Ba National Park
diversity Article The Presence of IUCN Red List Tree Species in Dependence of Site Characteristics in the Vietnamese Cat Ba National Park Van Vien Pham 1,2,* , Christian Ammer 2 and Peter Annighöfer 2 1 Forestry Faculty, Northeast College of Forest and Agriculture, Quangninh 207657, Vietnam 2 Silviculture and Forest Ecology of the Temperate Zones, Georg-August-University Göttingen, Büsgenweg 1, 37077 Göttingen, Germany; [email protected] (C.A.); [email protected] (P.A.) * Correspondence: [email protected]; Tel.: +49-551-3933-672 Received: 31 January 2020; Accepted: 13 March 2020; Published: 17 March 2020 Abstract: Rare or endangered tree species are important components of forest ecosystems and play a crucial role in management and conservation. Understanding what influences their presence is critical for managers, conservationists and planners. This study presents results of a comprehensive inventory of the tree species and site characteristics in the Vietnamese Cat Ba National Park (CBNP). An adaptive cluster sampling technique was applied to study the effect of human disturbance, soil properties, and terrain conditions on the presence of IUCN Red List tree species (all individuals > 5 cm diameter at breast height) in three strictly protected areas in CBNP, which have varying levels of isolation. Data from 239 sample plots (500 m2 each) were analyzed. Tree species recorded during the inventory were assigned to two categories: IUCN Red List and other. Our results showed that site characteristics differed in the three protected areas along with the presence of IUCN Red List tree species. IUCN Red List tree species were more frequently found on less favorable soils (low soil depth) and in terrain with more pronounced slopes and with a higher rock surface area (%). -
Tree Species Diversity and Utilities in a Contracting Lowland Hillside Rainforest Fragment in Central Vietnam

ETH Library Van and Cochard Forest Ecosystems (2017) 4:9 DOI 10.1186/s40663-017-0095-x RESEARCH Open Access Tree species diversity and utilities in a contracting lowland hillside rainforest fragment in Central Vietnam Yen Thi Van1 and Roland Cochard2* Abstract Background: Within the highly bio-diverse ‘Northern Vietnam Lowland Rain Forests Ecoregion’ only small, and mostly highly modified forestlands persist within vast exotic-species plantations. The aim of this study was to elucidate vegetation patterns of a secondary hillside rainforest remnant (elevation 120–330 m, 76 ha) as an outcome of natural processes, and anthropogenic processes linked to changing forest values. Methods: In the rainforest remnant tree species and various bio-physical parameters (relating to soils and terrain) were surveyed on forty 20 m × 20 m sized plots. The forest's vegetation patterns and tree diversity were analysed using dendrograms, canonical correspondence analysis, and other statistical tools. Results: Forest tree species richness was high (172 in the survey, 94 per hectare), including many endemic species (>16%; some recently described). Vegetation patterns and diversity were largely explained by topography, with colline/sub-montane species present mainly along hillside ridges, and lowland/humid-tropical species predominant on lower slopes. -
Complexity of the Socio-Ecological Dynamics in Hong Ha Commune in the Vietnamese Highland—A Review Through the Coupled Human and Natural Systems Framework

However, numerous recent case studies in the Vietnamese highland found that socio-ecological dynamics were highly complex on a local scale, resulting in unintended policy impacts and varying policy success among regions. While such complexity has become apparent, it has been difficult to understand and compare between regions, as assessment methods and targeted aspects of socio-ecological dynamics differed between case studies. In this review, complex socio-ecological dynamics in Hong Ha Commune in Thua Thien Hue Province were identified in published case studies and organized into complexity features based on the coupled human and natural systems (CHANS) framework, to make information more accessible and comparable under the widely applied framework. -

Tree Species Diversity and Utilities in a Contracting Lowland Hillside Rainforest Fragment in Central Vietnam Yen Thi Van1 and Roland Cochard2*
Van and Cochard Forest Ecosystems (2017) 4:9 DOI 10.1186/s40663-017-0095-x RESEARCH Open Access Tree species diversity and utilities in a contracting lowland hillside rainforest fragment in Central Vietnam Yen Thi Van1 and Roland Cochard2* Abstract Background: Within the highly bio-diverse ‘Northern Vietnam Lowland Rain Forests Ecoregion’ only small, and mostly highly modified forestlands persist within vast exotic-species plantations. The aim of this study was to elucidate vegetation patterns of a secondary hillside rainforest remnant (elevation 120–330 m, 76 ha) as an outcome of natural processes, and anthropogenic processes linked to changing forest values.

Vegetation patterns and diversity were largely explained by topography, with colline/sub-montane species present mainly along hillside ridges, and lowland/humid-tropical species predominant on lower slopes. Scarcity of high-value timber species reflected past logging, whereas abundance of light-demanding species, and species valued for fruits, provided evidence of human-aided forest restoration and ‘enrichment’ in terms of useful trees. Exhaustion of sought-after forest products, and decreasing appreciation of non-wood products concurred with further encroachment of exotic plantations in between 2010 and 2015. Regeneration of rare tree species was reduced probably due to forest isolation.
