This feature layer contains the permanent sample plot (PSP) database. The database was designed and constructed by GIS and Mapping Division, Resource Support Section. The Forest Ecosystem Management Division are the authoritative owners of this dataset.
<p style='text-align:left;'><span style='text-align:justify;'><b>Background</b></span></p><p style='text-align:left;'><span style='text-align:justify;'>In <b>1975</b>, the Department of Forestry began a new management inventory designed to provide statistics of forest lands and timber volumes in a form that could be used to develop Forest Management Plans. This involved measuring over 500 Temporary Sample Plots (TSP) and measuring or remeasuring nearly 100 Stand Monitor Plots (SMP) each year. The SMPs were designed to provide information which would allow updating of inventory cover types between subsequent inventories.</span></p><p style='text-align:left;'><span style='text-align:justify;'>In <b>1985</b>, nearing the completion of the second cycle of measuring TSPs, the focus began to change. It was felt that volume estimates acquired through TSPs were adequate for most strata and more emphasis be centered around collecting data on growth and yield. This led to the start of a Permanent Sample Plot (PSP) database. The program focused on establishing PSPs in regenerating and immature stand types. This focus continued between 1985 and 1991.</span></p><p style='text-align:left;'>In <b>1992</b>, an evaluation of the existing PSP program and an understanding of the provinces need for growth and yield information led to the design of a 1,000 plot program focusing on growth and yield data collection. Since 1992, additional measurements have been added to the PSP program at the request of various data users. These include Damman Site Type (soils and vegetation), Hare Pellets, Woody Debris, and Song Birds.</p><p style='text-align:left;'>In <b>2007</b>, the Newfoundland Forest Service began to use data loggers for collecting PSP data in the field. This speeds the data input process from the previous paper based system so that the data collected can be used shortly after the field season ends. The program also has controls to aid in avoiding errors during data entry; previously, errors were not detected until subsequent data analysis long after the plot measurements were completed.</p><p style='text-align:left;'>In <b>2024</b>, the PSP database underwent a significant overhaul, involving a redesign of the 2007 Microsoft Access database and enabling data collection using more modern smartphone and tablet technology. This required the engineering of the database within the Oracle Forestry Enterprise geodatabase and management of data within the ArcGIS Enterprise environment. Data loggers have been replaced and now use iOS and Android technology to collect and measure PSPs within the ArcGIS Field Maps application.</p><p style='text-align:left;'>The data within this feature layer is updated <b>daily</b> at 24-hour intervals, beginning at 6:00PM NST. Information within this layer represents the most up-to-date and accurate information currently available.</p><p style='text-align:left;'><b>Objective</b></p><p>The objectives of the Permanent Sample Plot Program are to provide stand growth data that can be used to calibrate and validate stand growth projection models and have a network of plots sufficient to sample the important stand conditions at an acceptable intensity. More specifically, the goal is to maintain a PSP program of at least 1,000 plots in natural and managed stands.</p><p>The PSP Program incorporates measurement of other stand conditions and variables as deemed needed by the users of the data.</p><p><b>Establishment and Allocation Procedures</b></p><p></p><p>The allocation is based on proportional representation of stands by Strata (Working Group, Age Class and Site Class in a Management District). The actual plot locations are randomly located within the district and within the stand to avoid bias. As plots are lost to various disturbances, a new plot will be:</p><p></p><ul><li>Re-established at the same site</li><li>Established as a replacement in the same stratum</li><li>Established in a strata type which is being under-represented, if the lost stratum is already well represented.</li></ul><div><b>Data Currency</b></div><div><b><br /></b></div><div><span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif;'><font size='3'>The data within this feature layer is updated daily at 24-hour intervals, beginning at 6:00PM NST.
