“…The dramatic increase in lianas that we observed can substantially alter the functioning of tropical forests. Lianas substantially depress tree performance (da Cunha Vargas et al, 2020;Schnitzer & Bongers, 2002;Toledo-Aceves, 2015); experimental evidence has shown that lianas significantly reduce tropical tree growth, recruitment, reproduction and survival (Estrada-Villegas & Schnitzer, 2018;Garcia-Leon et al, 2018). As lianas increase in abundance, so may their negative effects on such emergent processes as forest-level carbon sequestration and storage (van der Heijden et al, 2013;Schnitzer et al, 2014), as well as tree diversity and composition (Schnitzer, 2018).…”

Local canopy disturbance as an explanation for long‐term increases in liana abundance

Canopy disturbance explains liana abundance and distribution within tropical forests and thus may also explain the widespread pattern of increasing liana abundance; however, this hypothesis remains untested. We used a 10‐year study (2007–2017) of 117,100 rooted lianas in an old‐growth Panamanian forest to test whether local canopy disturbance explains increasing liana abundance. We found that liana density increased 29.2% and basal area 12.5%. The vast majority of these increases were associated with clonal stem proliferation following canopy disturbance, particularly in liana‐dense, low‐canopy gaps, which had far greater liana increases than did undisturbed forest. Lianas may be ecological niche constructors, arresting tree regeneration in gaps and thus creating a high‐light environment that favours sustained liana proliferation. Our findings demonstrate that liana abundance is increasing rapidly and their ability to proliferate via copious clonal stem production in canopy gaps explains much of their increase in this and possibly other tropical forests.

“…Their attributes make them good raw material for basketwork and other handicraft artefacts. The high growth rates of some species, and the rapid colonization of forest edges and early successional phases cause them to be abundant elements in secondary forests and altered fragments [ 16 – 18 ]. Many lianas have great capacity of regenerating after damage, so that a new branch quickly replaces a damaged branch [ 19 ].…”

“…In many species of lianas several stems may be ramets of the same genet, resulting from vegetative reproduction through stolons or rooting of stems [ 19 – 21 ]. Despite attributes favouring their increase in abundance in primary and secondary forests [ 16 – 18 ], some species are undergoing population declines due to overexploitation [ 5 , 22 – 24 ] or other processes [ 25 ].…”

The exploitation of non-timber forest products may be an opportunity to reconcile the utilization of biological resources with biodiversity conservation. In Southern Brazil, the exploitation of liana stems for handicraft makes up an important part of the income of indigenous Kaingang people. In this study we evaluated the effects of stem harvesting on the survivorship of Forsteronia glabrescens Müll.Arg, the most exploited liana species in the region. We marked and monitored the survivorship, sprouting, changes in stem diameter and resource yield in control and harvested plots with two different resting times–six and twelve months. We associated variables of interest with individual attributes, harvesting regime and vegetation descriptors through linear mixed modelling. Survivorship and resource yield were lower in the harvested groups than in the control group, although the mean stem diameter was higher. Plants with larger stem diameter presented higher survival odds. Either six or twelve months of resting between harvests were not sufficient to recompose the yield and compensate mortality. Harvesting twice a year increases yield but reduces survivorship. Our results point that the sustainable exploitation of F. glabrescens require either large areas, low pressure or resting periods longer than the ones we tested.
