Long-term effects of intercropping on multi-trophic structure and bio-thermodynamic health of mixed Eucalyptus-native tree plantations

1. The intercropping approach of Eucalyptus and native trees has been widely recommended, as an ideal replacement for monoculture Eucalyptus plantations (EUs), to ameliorate global biodiversity loss and mitigate environmental change. However, both suitable native tree species and the best intercropping ratio between Eucalyptus and native trees have not been determined. 2. To fill this gap, a four-level intercropping gradient of Eucalyptus urophylla planted with eight native tree species was set up (i.e., 20%NS, 30%NS, 40%NS, 50%NS), monitored and compared to a monoculture E. urophylla plantation (EU) and a randomly mixed plantation of nine native tree species (NS) in southern China. 3. The results showed that the intercropping ratio of Eucalyptus and native trees had a long-term effect on tree layer structure and health status and a cascading effect on the thermodynamic health state of soil microbes. Shade-tolerant woody species are more suitable for intercropping with Eucalyptus. Intercropping plantations with not less than 30% native trees were more favorable for long-term survival and growth of both planted Eucalyptus and native trees and provided much more favorable conditions for the natural immigration of other native trees, which leads to a healthy plant community with significantly higher eco-exergy compared to EU. The initial mixing ratio between Eucalyptus and high diversity native trees affected soil fertility through its long-term effects on the biodiversity and bio-thermodynamic state of trees and soil microbes. 4. Synthesis and applications. Our results highlight the long-term positive effect of the intercropping ratio of Eucalyptus and high diversity native trees on multi-trophic biodiversity conservation, bio-thermodynamic health development, and soil fertility conservation. In the conversion of monoculture Eucalyptus plantations (EU) to multi-species plantations, it is recommended to mix more than 30% native tree species that have different ecological niches with Eucalyptus.

Annaberg Plantation Usa, Mesh

Mesh from photogrammetry, drone Trimble UX5 Site Description The Annaberg Sugar Plantation in the Virgin Islands is part of one of the largest historic migrations of people and resources throughout the world. For centuries, the Virgin Islands was a crossroads for indigenous peoples, colonial powers, and the transatlantic slave trade. The plantation structures that the National Park Service preserves on the site today demonstrate the agricultural success of the Danish Colonial era, but also its human cost. A 40-foot high windmill constructed with sails to direct the wind was state of the art at the time of its completion in 1805. Not far from the windmill, built into the foundation of the sick house, the Annaberg "Dungeon" served as a means of punishment for enslaved laborers....more info: https://doi.org/10.26301/vv0h-dq68 CyArk 2019: Annaberg Plantation - LiDAR - Terrestrial , Photogrammetry .

Industrial and Smallholder Oil Palm Plantation Expansion in Indonesia from 2001 to 2019

The dataset contains  wall-to-wall maps of the annual expansion of industrial and smallholder oil palm plantations from 2001 to 2019 generated from interpretation of annual LANDSAT composites, SPOT-6 and UAV imagery. We define an oil palm plantation as an area of land planted with oil palm trees (Elaeis guineensis Jacq.).  Industrial plantations are intensively managed large-scale, typically covering several thousand hectares of land, plantations owned by companies. They exhibit distinctive linear boundaries while harvesting trails are laid out in grids on level land or follow contours on hilly terrain. Smallholder plantations are typically smaller — < 25 hectares according to government definition — although wealthy individuals sometimes own several hundred hectares  — and their spatial patterns are less consistent. Smallholder landscapes sometimes form a mixed mosaic with one or more other crops and types of landcover , or a large homogeneous landscape , or resemble industrial plantings though generally smaller and with less consistent structure. The datasets are in shapefile format with the following columns: Year: The year an area was converted to oil palm. This is the year an area of either Forest or Non-Forest transitioned to either industrial or smallholder oil palm. Class: The type of plantation that exists as of year 2019. Class has category:  ‘IOPP’ for Industrial Oil Palm Plantation or 'Smallholder'. Gridcode: A code for the year the annual Tree Loss dataset (version 1.7) - developed at University of Maryland (Hansen et al. 2013) - recorded a loss, and whether this is loss of trees in the forest or loss of non-forested trees. This column can be ignored. <ul> <li>1xx : Year forest loss detected, where xx represents the last 2 digits of the year (from 2001 to 2019) when the loss happened. For example, 105 indicates forest loss in 2005.</li> <li>300 : Non-forest since 2000.</li> <li>3xx : Year tree (non-forest) loss detected, where xx represents the last 2 digits of the year (from 2001 to 2019) when the loss happened. For example, 305 indicates tree loss in 2005 in non-forest areas with trees.</li> </ul> F2000 to F2019: The annual land cover types (Forest or Non forest) that existed before oil palm plantations replaced them. TDelay : The time delay (in number of years) beween the year an area lost its forest cover and the year  it was developed as a plantation. If Tdelay = 0, the area was developed as a plantation in the same calendar year that it lost forest cover, or the area was already not forest in 2000. CompDriven : The year an area was developed as a plantation and lost its forest cover. We reasoned that industrial plantations developed in the same year as forest clearance are likely to be responsible for that clearance, hence the term Company-driven deforestation. If CompDriven = 0 the area lost its forest cover several years (at one year) before it was developed as a plantation.   Region: The name of the region considered (Sumatra, Kalimantan, Java, Sulawesi, Maluku and Papua) AreaHA: The area in hectares

Effects of long-term nitrogen addition on water use by Cunninghamia lanceolate in a subtropical plantation

The deposition of reactive nitrogen (N) has substantially increased in subtropical regions due to human activities. However, the effects of long-term N addition on the water-use efficiency of subtropical forests are poorly understood. Here, we conducted an 11-year experiment in a subtropical Cunninghamia lanceolate plantation with four N-addition levels: N0, N1, N2, and N3 (equivalent to 0, 6, 12, and 24 g of N m-2 yr-1, respectively). A thermal dissipation probe system was used to calculate sap flow and plant biomass carbon was assessed by field investigation. The whole-plant water use and water-use efficiency were estimated. In addition, the δ13C of tree rings was used to indicate the plant intrinsic water-use efficiency. The results showed that N3 significantly increased the annual sap flow velocity, especially in summer and winter. Annual water use, plant growth, and water-use efficiency did not significantly differ among the N treatments, but water use tended to be higher in N3 than in N0. Furthermore, the reduction of δ13C between the pre-N treatment period and the post-N treatment period was 3.02%, 3.26%, 3.58%, and 5.28% for N0, N1, N2 and N3, respectively, which supported the inference that N addition could enhance water use. We conclude that long-term addition of high levels (but not of low levels) of N increased whole-plant water use in C. lanceolate plantations. Our results indicate that N deposition accompanied by high temperature and drought events may negatively affect water balance in subtropical forests.

Meteorological and Flux Data in Two Rubber Plantations and a Natural Forest in Mainland Southeast Asia

Rubber plantations have rapidly replaced natural forests in Mainland Southeast Asia, yet the relevant impacts on the terrestrial carbon cycle remain uncertain, especially with an increase in drought frequency. Based on the meteorological and flux data from two rubber sites and one natural forest site, our study investigated the rubber ecosystem fluxes in a marginal (drier) plantation and their responses to drought 2015/2016 compared to a local natural forest, and the differences in ecosystem fluxes and their climatic drivers between the marginal plantation and a traditional humid plantation.
