“…In contrast, others claimed that bamboos, being an evergreen plant, could be easily detected and quantified using RS especially in the winter or in the dry season when other trees lose their green colour due to leaf senescence (Ferreira et al, 2020). Despite these challenges, there are some promising trials carried out in countries, such as China, India and Brazil, to quantify bamboo forests using RS (Bharadwaj et al, 2003;Linderman et al, 2004;Tang et al, 2016). Dida et al (2021) carried out an extensive study to quantify bamboo resources in the Philippines, but omitting those in the forest understory due to low visibility and limited inventory data for validation.…”
