We assessed monitoring possibilities, ranging from scientist-driven to those undertaken by local people, for the current proposed indicators to measure progress towards goals and targets in this framework. Of the 291 indicators, 159 (55%) require monitoring by scientists, whereas 132 (45%) can involve citizens. Contrary to expectations, the potential for citizen participation is lower than for the Aichi Targets. Involving citizens and Indigenous Peoples in the collection and interpretation of environmental data can support monitoring of progress and improve conservation outcomes, as demonstrated by global community monitoring and citizen science.

Vertebrate population cycles in northern latitudes are driven by both endogenous and exogenous factors. Suggested causes of mysterious disappearances documented for populations of the Neotropical, herd-forming, white-lipped peccary (Tayassu pecari, henceforth “WLP”) include large-scale movements, overhunting, extreme floods, or disease outbreaks. By analyzing 43 disappearance events across the Neotropics and 88 years of commercial and subsistence harvest data for the Amazon, we show that WLP disappearances are widespread and occur regularly and at large spatiotemporal scales throughout the species’ range. We present evidence that the disappearances represent 7–12-year troughs in 20–30-year WLP population cycles occurring synchronously at regional and perhaps continent-wide spatial scales as large as 10,000–5 million km2. This may represent the first documented case of natural po...

Mysterious disappearances of populations of the Neotropical, herdforming white-lipped peccary (Tayassu pecari, henceforth “WLP”) have been anecdotally documented and explained as local events resulting from migratory movements or overhunting2,3,4, or as disease outbreaks5,6, and have not been considered in the context of large-scale species-specific population dynamics. Here we present evidence that WLP disappearances represent troughs in population cycles that occur with regular periodicity and are synchronized at regional and perhaps continent-wide spatial scales. Analysis of 43 disappearance events and 88 years of commercial and subsistence harvesting data reveals boom – bust population cycles lasting from 20 to 30 years, in which a rapid population crash occurring over 1 to 5 years is followed by a period of absence of 7 to12 years and then a slow growth phase. Overhu...

Veitch is among the 24 endangered orchid species of Rio de Janeiro city. This species, endemic to Rio de Janeiro state mountains, was known to occur only at the top of the most-visited mountains in town, on Pão de Açucar rock and Pedra da Gávea rock. Today the Pão de Açucar rock population may well be extinct because of over-collecting practices, but some plants can still be found at Pedra da Gávea rock, in spite of past over-collecting at the site. Currently the CORES (Coastal Orchid Restoration) Project has adopted a conservation strategy that covers both ex-situ and in-situ conservation of the species. Following the action plan for conservation, developed by the IUCN Orchid Specialist Group, the project has three objectives: (1) Determine the conservation status of Laelia lobata, analyzing population demography, floral biology, and population genetics of three samples (Pão de Açucar rock, Pedra da Gávea rock, and ex-situ propagates); (2) Micro-propagat...
