Analysis of geographic and taxonomic groups informs conservation of Rhododendron subgenus Vireya (Ericaceae) Naturalis
MacKay, M.; Smith, G.; Gardiner, S.E..
Although Rhododendron subg. Vireya, comprising 400 taxa, is one of the largest plant genera in Southeast Asia, with taxa found throughout the region, it has a significant conservation problem, with conservation status assessments in 2011 and 2015 placing 201 taxa in an IUCN Red List threat category. Plant conservation is driven by the Global Strategy for Plant Conservation, with Target 8 requiring 75 % of threatened plant taxa to be conserved in ex situ collections, by 2020. To date there has been limited analysis of conservation priorities for subg. Vireya, or any consideration of how its geographic characteristics, complex taxonomy, and existing ex situ collections might influence priorities. We analyse the IUCN Red List status of geographic origins and...

VALUING BOTANIC COLLECTIONS: A COMBINED TRAVEL-COST AND CONTINGENT VALUATION SURVEY IN AUSTRALIA AgEcon
Mwebaze, Paul; Bennett, Jeffrey W..
The economic value of biological collections in three major botanic gardens in Australia was estimated using the Travel-Cost (TC) and Contingent Valuation (CV) methods. The study used truncated count data models to control for the non-negative integer and truncation properties of the number of visits to botanic gardens in Canberra, Melbourne and Sydney. We estimate consumer surplus values of approximately $34 per trip to each botanic garden, resulting in the total social welfare estimate of approximately $96.9 million in 2010 Australian dollars. This result is relatively high compared to similar studies conducted in other countries. Willingness to pay (WTP) for entry fees and or higher parking charges for access to botanic gardens were also investigated....
