This article overviews the prairie and tree planting tool or PT² (1.0), an online GIS-based decision support tool for landowners interested in exploring opportunities to plant prairie or trees in and around their farm fields for conservation or production purposes. PT² 1.0 can be found online at: https://pt2.nrem.iastate.edu/. With the PT² (1.0) users locate farm fields of interest in an online aerial photograph and mapping geographic information system (GIS). Users explore areas they are considering for prairie or tree cover by examining different data layers: soil maps, 2-foot contour topography maps, LiDAR hillshade maps, and a map of current land values based on estimated land rent. Users then utilize scaled dimensional drawing tools to measure and delineate areas of interest for planting trees and or prairie. Once an area is delineated, users select from drop-down menus prairie seed mixes or woody species that are suitable for the soils present, and users can select basic long-term management options. PT² (1.0) estimates total annualized costs for tree or prairie establishment, long-term management, and opportunity costs (based on area weighted expected soil rent), and factors in the potential benefit of utilizing government cost-share programming, e.g., Environmental Quality Incentive Program or the Conservation Reserve Program. Key data layers are currently functional in Iowa, likewise the financial data underlying the cost analysis are specific to Iowa. PT² (1.0) is, however, open source and open code and guidance is provided regarding how to access and adapt the data for use in other states.

本文概述了草原和树木种植工具或 PT ² (1.0)，这是一种基于 GIS 的在线决策支持工具，适用于有兴趣探索在其农田及其周围种植草原或树木以进行保护或生产的机会的土地所有者。 PT ² 1.0 可在线找到：https://pt2.nrem.iastate.edu/。借助 PT ² (1.0)，用户可以通过在线航空照片和测绘地理信息系统 (GIS) 定位感兴趣的农田。用户通过检查不同的数据层来探索他们正在考虑的草原或树木覆盖区域：土壤图、2 英尺等高线地形图、激光雷达山体阴影图以及基于估计土地租金的当前土地价值图。然后，用户利用比例尺绘图工具来测量和描绘种植树木和/或草原的感兴趣区域。一旦划定了一个区域，用户就可以从下拉菜单中选择适合当前土壤的草原种子混合物或木本物种，并且用户可以选择基本的长期管理选项。 PT ² (1.0) 估算树木或草原种植、长期管理和机会成本（基于面积加权预期土壤租金）的年化总成本，以及利用政府成本分摊计划的潜在效益因素，例如，环境质量激励计划或保护储备计划。关键数据层目前在爱荷华州发挥作用，同样，成本分析所依据的财务数据也是爱荷华州特有的。然而，PT ² (1.0) 是开源和开放代码，并提供了有关如何访问和调整数据以在其他州使用的指南。
