Mongabay: It's not easy to measure carbon in mountain forest ecosystems. For one thing, climbing into these forests can be difficult, exhausting, and even treacherous. For another, many mountain rainforests are almost constantly blanketed by clouds-hence the term "cloud forest"-making it problematic to measure above-ground carbon storage from the air or satellite. But a new review study in Biogeosciences found that many estimates of carbon storage in montane tropical forests have been largely underestimated....
