Forest protection policies potentially reduce deforestation and re-direct agricultural expansion to already-cleared areas. Using satellite imagery, we assessed whether deforestation for conversion to pasture and cropland decreased in the lowlands of northern Costa Rica following the 1996 ban on forest clearing, despite a tripling of area under pineapple cultivation in the last decade. We observed that following the ban, mature forest loss decreased from 2.2% to 1.2% per year, and the proportion of pineapple and other export-oriented cropland derived from mature forest declined from 16.4% to 1.9%. The post-ban expansion of pineapples and other crops largely replaced pasture, exotic and native tree plantations, and secondary forests. Overall, there was a small net gain in forest cover due to a shifting mosaic of regrowth and clearing in pastures, but cropland expansion decreased reforestation rates. We conclude that forest protection efforts in northern Costa Rica have likely slowed mature forest loss and succeeded in re-directing expansion of cropland to areas outside mature forest. Our results suggest that deforestation bans may protect mature forests better than older forest regrowth and may restrict clearing for large-scale crops more effectively than clearing for pasture.

hi there my name's that if in in key issues in a clever university and I'm studying the effects of conservation on tropical deforestation and fragmentation about to talk to today about a paper Neuralink street is innovative conservation policies and their effects on rain forests in northern history to
load tropical rain forests are under threat globally from our cultural expansion but those threats a change to the last couple decades to
illustrate this is a pineapple field not a pasture the expansion of intensively cultivated monoculture crops in the rain forest

decreased and 2 comma decimal 2 per cent to 1 comma decimal 2 per cent per year most of the time deforestation occurred in a 4 year period tween 2001 and 2005 a time that coincides with when no more like basically permits are available from the national government while the legally for stationary 1 per cent is not ideal over the long term it does represent improved almost 50 per cent over the prevent time period goal slowing mature forest loss has been partially achieved furthermore
the band appears to have redirected the expansion of problems linking forest despite a tripling in area and upon overcultivation last decade the proportion of pineapple other exported cropland rife mature forest declined from 16 comma decimal 4 per cent to 1 comma decimal 9 per cent as you can see in this figure the post then expansion of pineapples other crops larger placed pasture is Iike new tree plantations and secondary forests after the ban at culture
