Here, we present an analysis of the changes in stem density, biomass, and species richness of lianas and self-supporting plants during tropical forest succession. We surveyed lianas ≥0.5 cm diameter at breast height (dbh) and self-supporting plants ≥2.5 cm dbh in 0.1 ha inventory plots in a chronosequence of 30 sites in northeastern Costa Rica, 23 sites on abandoned pastures 10–44 years of age, and seven sites in old-growth forest. Stem density of self-supporting plants showed no predictable chronosequence trend, but liana stem density declined significantly with forest age. Aboveground biomass of self-supporting vegetation increased rapidly during succession, with forests 31–44 years exhibiting higher levels of biomass than old-growth forests. Liana biomass accumulated more slowly, with the highest levels in old-growth sites. Species richness of self-supporting vegetation increased significantly during succession, but species richness of lianas showed no change or a slight decline with forest age, depending on the method of assessment. The differences between tree and liana responses during succession stem from the unique physiology and life history traits of lianas.

An analysis of above-ground biomass recovery during secondary succession in forest sites and plots, covering the major environmental gradients in the Neotropics. Plus de la moitié des forêts tropicales du monde sont le produit d'une croissance secondaire, suite à des perturbations anthropiques. Il est donc important de savoir à quelle vitesse ces forêts secondaires se rétablissent suffisamment pour fournir des services écosystémiques équivalents à ceux des forêts anciennes. Ces auteurs se concentrent sur la séquestration du carbone dans les forêts néotropicales et constatent que l'absorption de carbone est beaucoup plus élevée que dans les forêts anciennes, ce qui permet de récupérer 90 % des stocks de carbone en 66 ans en moyenne, mais il existe également une grande variation du potentiel de récupération. Ces connaissances pourraient aider à évaluer les implications de la perte de forêts — et le potentiel de rétablissement — dans différentes zones. Le changement d'affectation des terres ne se produit nulle part plus rapidement que dans les tropiques, où le déséquilibre entre la déforestation et la repousse forestière a des conséquences importantes sur le cycle mondial du carbone1. Cependant, une incertitude considérable demeure quant au taux de récupération de la biomasse dans les forêts secondaires et à la manière dont ces taux sont influencés par le climat, le paysage et l'utilisation antérieure des terres2,3,4. Nous analysons ici la récupération de la biomasse aérienne au cours de la succession secondaire dans 45 sites forestiers et environ 1 500 parcelles forestières couvrant les principaux gradients environnementaux des Néotropiques. Les forêts secondaires étudiées sont très productives et résilientes. La récupération de la biomasse aérienne après 20 ans était en moyenne de 122 mégagrammes par hectare (Mg ha−1), ce qui correspond à une absorption nette de carbone de 3,05 Mg C ha−1 an−1, soit 11 fois le taux d'absorption des forêts anciennes. Les stocks de biomasse aérienne ont pris un temps médian de 66 ans pour se rétablir à 90 % des anciennes valeurs de croissance. La récupération de la biomasse aérienne après 20 ans a varié de 11,3 fois (de 20 à 225 Mg ha−1) d'un site à l'autre, et cette récupération a augmenté avec la disponibilité en eau (pluviométrie locale plus élevée et déficit en eau climatique plus faible). Nous présentons une carte de récupération de la biomasse d'Amérique latine, qui illustre la variation géographique et climatique du potentiel de séquestration du carbone au cours de la repousse forestière. La carte soutiendra les politiques visant à minimiser la perte de forêts dans les zones où la résilience de la biomasse est naturellement faible (telles que les régions forestières saisonnièrement sèches) et à promouvoir la régénération et la restauration des forêts dans les zones tropicales humides de plaine à forte résilience de la biomasse. Un análisis de la recuperación de biomasa sobre el suelo durante la sucesión secundaria en sitios forestales y parcelas, que cubre los principales gradientes ambientales en el Neotrópico. Más de la mitad de los bosques tropicales del mundo son producto de un crecimiento secundario, tras una perturbación antropogénica. Por lo tanto, es importante saber qué tan rápido se recuperan estos bosques secundarios lo suficiente como para proporcionar servicios ecosistémicos equivalentes a los de los bosques primarios. Estos autores se centran en el secuestro de carbono en los bosques neotropicales y encuentran que la absorción de carbono es mucho mayor que en los bosques primarios, lo que permite la recuperación del 90% de las reservas de carbono en un promedio de 66 años, pero también hay una amplia variación en el potencial de recuperación. Este conocimiento podría ayudar a evaluar las implicaciones de la pérdida de bosques, y el potencial de recuperación, en diferentes áreas. El cambio en el uso de la tierra no ocurre en ninguna parte más rápidamente que en los trópicos, donde el desequilibrio entre la deforestación y el rebrote de los bosques tiene grandes consecuencias para el ciclo global del carbono1. Sin embargo, persiste una considerable incertidumbre sobre la tasa de recuperación de biomasa en los bosques secundarios y cómo estas tasas están influenciadas por el clima, el paisaje y el uso previo de la tierra2,3,4. Aquí analizamos la recuperación de biomasa sobre el suelo durante la sucesión secundaria en 45 sitios forestales y alrededor de 1.500 parcelas forestales que cubren los principales gradientes ambientales en el Neotrópico. Los bosques secundarios estudiados son altamente productivos y resilientes. La recuperación de biomasa sobre el suelo después de 20 años fue en promedio de 122 megagramas por hectárea (Mg ha−1), lo que corresponde a una absorción neta de carbono de 3,05 Mg C ha−1 año−1, 11 veces la tasa de absorción de los bosques antiguos. Las existencias de biomasa sobre el suelo tardaron una mediana de 66 años en recuperarse hasta el 90% de los valores de crecimiento antiguo. La recuperación de biomasa sobre el suelo después de 20 años varió 11,3 veces (de 20 a 225 Mg ha-1) entre los sitios, y esta recuperación aumentó con la disponibilidad de agua (mayores precipitaciones locales y menor déficit climático de agua). Presentamos un mapa de recuperación de biomasa de América Latina, que ilustra la variación geográfica y climática en el potencial de secuestro de carbono durante el recrecimiento forestal. El mapa apoyará las políticas para minimizar la pérdida de bosques en áreas donde la resiliencia de la biomasa es naturalmente baja (como las regiones forestales estacionalmente secas) y promoverá la regeneración y restauración de bosques en áreas tropicales húmedas de tierras bajas con alta resiliencia a la biomasa. An analysis of above-ground biomass recovery during secondary succession in forest sites and plots, covering the major environmental gradients in the Neotropics. More than half the world's tropical forests are the product of secondary growth, following anthropogenic disturbance. It is therefore important to know how quickly these secondary forests recover sufficiently to provide ecosystem services equivalent to those of old-growth forest. These authors focus on carbon sequestration in Neotropical forests, and find that carbon uptake is much higher than in old-growth forest, allowing recovery to 90% of the carbon stocks in an average of 66 years, but there is also wide variation in recovery potential. This knowledge could help assess the implications of forest loss — and potential for recovery — in different areas. Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2,3,4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major environmental gradients in the Neotropics. The studied secondary forests are highly productive and resilient. Aboveground biomass recovery after 20 years was on average 122 megagrams per hectare (Mg ha−1), corresponding to a net carbon uptake of 3.05 Mg C ha−1 yr−1, 11 times the uptake rate of old-growth forests. Aboveground biomass stocks took a median time of 66 years to recover to 90% of old-growth values. Aboveground biomass recovery after 20 years varied 11.3-fold (from 20 to 225 Mg ha−1) across sites, and this recovery increased with water availability (higher local rainfall and lower climatic water deficit). We present a biomass recovery map of Latin America, which illustrates geographical and climatic variation in carbon sequestration potential during forest regrowth. The map will support policies to minimize forest loss in areas where biomass resilience is naturally low (such as seasonally dry forest regions) and promote forest regeneration and restoration in humid tropical lowland areas with high biomass resilience. تحليل لاسترداد الكتلة الحيوية فوق الأرض خلال التعاقب الثانوي في مواقع الغابات وقطع الأراضي، والتي تغطي التدرجات البيئية الرئيسية في المناطق المدارية الحديثة. أكثر من نصف الغابات الاستوائية في العالم هي نتاج نمو ثانوي، بعد الاضطرابات البشرية. لذلك من المهم معرفة مدى سرعة تعافي هذه الغابات الثانوية بما يكفي لتوفير خدمات نظام بيئي مكافئة لتلك الموجودة في الغابات القديمة النمو. يركز هؤلاء المؤلفون على عزل الكربون في الغابات المدارية الحديثة، ويجدون أن امتصاص الكربون أعلى بكثير منه في الغابات القديمة النمو، مما يسمح بالتعافي إلى 90 ٪ من مخزونات الكربون في متوسط 66 عامًا، ولكن هناك أيضًا تباينًا كبيرًا في إمكانات الاسترداد. يمكن أن تساعد هذه المعرفة في تقييم الآثار المترتبة على فقدان الغابات — وإمكانية التعافي — في مناطق مختلفة. لا يحدث تغير استخدام الأراضي في أي مكان بسرعة أكبر من المناطق المدارية، حيث يكون للاختلال بين إزالة الغابات وإعادة نمو الغابات عواقب كبيرة على دورة الكربون العالمية1. ومع ذلك، لا يزال هناك قدر كبير من عدم اليقين بشأن معدل استرداد الكتلة الحيوية في الغابات الثانوية، وكيف تتأثر هذه المعدلات بالمناخ والمناظر الطبيعية والاستخدام السابق للأراضي 2،3،4. نقوم هنا بتحليل استرداد الكتلة الحيوية فوق الأرض خلال التعاقب الثانوي في 45 موقعًا للغابات وحوالي 1500 قطعة غابات تغطي التدرجات البيئية الرئيسية في المناطق المدارية الحديثة. الغابات الثانوية المدروسة عالية الإنتاجية والمرونة. كان استرداد الكتلة الحيوية فوق الأرض بعد 20 عامًا في المتوسط 122 ميغاغرام لكل هكتار (Mg ha−1)، وهو ما يعادل امتصاصًا صافياً للكربون قدره 3.05 Mg C ha−1 سنة−1، أي 11 ضعف معدل امتصاص الغابات القديمة النمو. استغرقت مخزونات الكتلة الحيوية فوق الأرض وقتًا متوسطًا قدره 66 عامًا للتعافي إلى 90 ٪ من قيم النمو القديمة. تفاوت استرداد الكتلة الحيوية فوق الأرض بعد 20 عامًا 11.3 ضعفًا (من 20 إلى 225 ملليغرام هكتار−1) عبر المواقع، وزاد هذا الانتعاش مع توافر المياه (ارتفاع هطول الأمطار المحلية وانخفاض العجز المائي المناخي). نقدم خريطة استرداد الكتلة الحيوية لأمريكا اللاتينية، والتي توضح التباين الجغرافي والمناخي في إمكانات عزل الكربون أثناء إعادة نمو الغابات. ستدعم الخريطة السياسات الرامية إلى تقليل فقدان الغابات في المناطق التي تكون فيها مرونة الكتلة الحيوية منخفضة بشكل طبيعي (مثل مناطق الغابات الجافة الموسمية) وتعزيز تجديد الغابات واستعادتها في المناطق المنخفضة الاستوائية الرطبة ذات المرونة العالية للكتلة الحيوية.
