Blacks Mountain Experimental Forest site, station NADP Station CA96, Lassen Volcanic National Park-Manzanita Lake, study of sulfur from sulfate in wet deposition in units of kilogramsPerHectare on a monthly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Blacks Mountain Experimental Forest (BLA) contains sulfur from sulfate in wet deposition measurements in kilogramsPerHectare units and were aggregated to a monthly timescale.

Virgin Islands National Park: Coral Reef: Population Dynamics: Scleractinian corals
These data are evidence of the the long-term dynamics of shallow coral reefs along the south coast of St. John from as early as 1989. These data come from the long term site at 9 m depth known as Yawzi Point. These data are representative of the Video Transects (VT) starting in 1989 (see Edmunds and Wirman 1991, MEPS 78: 201-204). All images analyzed using 200 randoms dots placed at random on their surface and the substratum beneath each dot annotated (~371,800 decisions by Nov 2017). Hurricanes Irma and Maria struck in September 2017. Because of this, sampling was completed in July and November of 2017. Data are available upon request for 1989 (raw data lost), 1992, 1993, and 1994. These images were analyzed with a coarser resolution that is not consistent with the current format.
Tree cone presence and abundance from Niwot Ridge, Rollins Pass, and Rocky Mountain National Park, 2015-2018.
These data were collected to examine the determinants of individual tree cone presence and cone abundance for Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa) in the southern Rocky Mountains, USA. We monitored > 1600 Engelmann spruce and subalpine fir trees for cone presence (an indicator of reproductive maturity) and a subset of those trees for cone abundance (an indicator of seed production) from 2016-2018 in the Colorado Front Range. Cone presence was observed in 1-3 years (2015 or 2016-2018) in 15 plots and cone abundance was observed in 10 of 15 plots in three years (2016-2018). We measured the following for > 24 live trees for each species in each plot: cone presence and/or cone abundance, diameter at breast height, age, height class. For each plot, we measured stand density, basal area, and age of oldest tree to estimate the timing of stand initiation. This database includes three datasets: 1) description of plots (e.g. elevation, aspect, size), 2) cone presence data, and cone abundance data. See Andrus et al. 2020 for more details. References Andrus, R. A., Harvey, B. J., Hoffman, A., and Veblen, T. T.. 2020. Reproductive maturity and cone abundance vary with tree size and stand basal area for two widely distributed conifers.

Density estimates of African lions in Queen Elizabeth National Park
<p><span><span><span><span><span><span><span><span><span><span><span>African lions are declining across much of their range, yet robust measures of population densities remain rare. The Queen Elizabeth Conservation Area (QECA; 2400 km<sup>2</sup>) in East Africa's Albertine Rift has potential to support a significant lion population. However, QECA lions are threatened, and information on the status of lions in the region is lacking. Here, we use a spatially explicit search encounter approach to estimate key population parameters of lions in the QECA. We then compare home range sizes estimated from our models to those from a radio-collaring study implemented a decade earlier. We recorded 8243.5 km of search effort over 93 days, detecting 30 individual lions (16 female and 14 male) on 165 occasions at a rate of 2 lion detections/100 km<sup>2</sup>. Lion density in the QECA was 2.70 adult lions/100 km<sup>2</sup>(SD=0.47), while mean abundance was 71 individuals (SD=11.05). Worryingly, the movement parameter for male lions was 3.27 km and 2.22 km for females, suggesting >400%, and >100% increases in home range size, respectively, compared to a decade earlier. Sex ratio of lions in the QECA was lower (1 male: 0.75 females), when compared to a previously published review (mean=1:2.33). The large movements and skewed sex ratios we report on in this paper are likely a result of human driven prey depletion. Our results suggest lions in the QECA are in a precarious state and the lion densities are significantly lower than what they could be. As lions are under pressure throughout much of Africa, our study presents the utility of a census technique that could be used elsewhere as an early warning of lion declines. </span></span></span></span></span></span></span></span></span></span></span></p>
Data from: Understanding sentiment of national park visitors from social media data
<p>National parks are key for conserving biodiversity and supporting people´s well-being. However, anthropogenic pressures challenge the existence of national parks and their conservation effectiveness. Therefore, it is crucial to assess how people perceive national parks in order to enhance socio-political support for conservation. User-generated data shared by visitors on social media provide opportunities to understand how people perceive (e.g. preferences, feelings, opinions) national parks during nature-based recreational experiences. In this study, we applied methods from automated natural language processing to assess visitors' sentiment when describing experiences in Instagram posts geolocated inside four national parks in South Africa. We found that visitors' sentiment was positive, and mostly included emotions such as joy, anticipation, trust and surprise, with only a small occurrence of posts with negative feelings. Appreciation of nature, in association with a diverse set of other aspects, such as activities, geographical features and tourist attractions, was used to describe experiences related to nature, wilderness, traveling, holidays and adventures. The type of nature-based experience described by visitors was park specific, revealing different profiles of parks providing wildlife or scenery experiences. Findings support and highlight the societal role of national parks in providing visitors with opportunities to develop positive connections with nature. Social media data may be used to understand visitors' perceptions, and how the image of national parks is constructed by users in the virtual social environment. This may help inform management for promoting a high quality tourism experience, as well as conservation marketing aimed at fostering socio-political support for national parks and their long-term conservation effectiveness.</p>
