Results Summary The city of New Ulm spans 6,634 acres with 3,220 of those acres within the business & residential area outlined above. We estimate that there are about 52,000 trees within 66 feet of the roads in the business & residential area. The 2020 survey estimated a population change of -11% trees in New Ulm compared to the 2010 estimation. Out of the 3,220 surveyed acres, 98% (3,149 acres) is considered maintained while 2% (71 acres) is considered non-maintained. Only maintained areas are surveyed. Maintained areas are periodically mowed or fall within an artificial surface, (e.g. parking lot). Refer to Appendix A for more information on the 2020 data collection methods. Funding for this project was provided by the Minnesota Environment and Natural Resources Trust Fund as recommended by the Legislative-Citizen Commission on Minnesota Resources (LCCMR). 1 Page 6 of 18  2020 Summary Refer to Appendix B for a guide to all survey summary tables.

For a more in-depth summary for your community, conducting an independent tree inventory survey is recommended. Who: The data was collected by AmeriCorps members and college forestry interns with basic tree identification skills. Where: Interns collected data along transects following public roads in 305 of Minnesota’s most populated cities and towns. The number, length, and placement of transects were chosen to obtain a representative sample of trees within each community. Trees within 66’ of either side of the road were recorded in the survey. When: Data was collected in April through November of 2022, 2023, and 2024. What: Only trees with at least a 1 inch diameter at breast height (4.5 feet) were recorded in the survey. Trees with multiple stems were counted as a single individual, measured by the largest stem. Appendix B: Survey Summary Table Columns and Symbology Genus: The taxonomic group above species. We use genus to group together and summarize across similar species. Species: All tree species observed, grouped by genus. Data is reported for the individual species as well as the summarized “Total” by genus. “Total” summaries are not included for a genus with only one species observed. Population: The number of trees estimated to be within survey boundaries for a given species or genus total. The populations of all tree species within a genus will add up to approximately that genus’ total population. % of All Trees: The number of trees for a given species or genus compared to the total number of trees estimated in a community, expressed as a percent (# Trees in Species or Genus/# All Trees * 100 = % of All Trees). The % of All Trees for species within a genus will add up to approximately the % of All Trees for that genus’ total. Genus/Species % [Size Class]: This represents the percentage of trees that fall within a given size class for the given species or genus total. The four size class distribution percentages add up to approximately 100% within a species or genus total. 10 Page 15 of 18 [Size Class] % No Decline Noted: This describes the percent of alive trees for a given species/genus and size class that were not marked as having signs of decline in the survey. Dead trees were excluded from this calculation. Size Class: A tree’s size class is determined by the estimated DBH (diameter at breast height). The four size classes are: • Small: Less than 5 inches (DBH < 5”). • Medium: Between 5 and 10 inches (5” <= DBH < 10”). • Large: Between 10 and 24 inches (10” <= DBH < 24”). • Super: Greater than 24 inches (DBH >= 24”). Dash “-”: A dash was used in % No Decline Noted when there were no trees observed in that species or genus’ size class. % Dead: This is the percent of all trees within a given species or genus total that are dead. *Note: High percentages of dead or declining trees may misrepresent the overall health of species with low populations. This may occur when a species is rare in a community and the few trees recorded in the survey were all or mostly dead or declining. Appendix C: 2010 to 2020 Change Table Columns and Symbology Note: Twenty-four communities do not have a community change report because they were not surveyed in 2010. Population Change: This shows the approximate number of trees gained or lost per genus from 2010 to 2020 (2020 Population – 2010 Population). Population % Change: This describes how much a genus’ population increased or decreased from 2010 to 2020 (2020 Population/2010 Population - 1). A positive percent means the genus’ population increased, and a negative percent means the population decreased. Change in % [Size Class] Trees: This describes how the spread of trees within a size classes has changed from 2010 to 2020 for the given genus (2020 Size Class % - 2010 Size Class %). A negative value means the proportion of trees in that size class has decreased and a positive value means that the proportion of trees in that size class had increased. Change in % No Decline Noted: This describes whether the proportion of trees without any major decline or defects within a genus has increased or decreased from 2010 to 2020 (2020 Genus % No Decline Noted – 2010 Genus % No Decline Noted). This metric excludes dead trees and only compares alive trees without noted decline to declining alive trees. Dash “-”: A dash in Population % Change, Change in % [Size Class] Trees, and Change in % No Decline Noted is used when a genus was only observed in one survey cycle (2010 or 2020). These columns are excluded because there is not a second value to compare to. Population 11 Page 16 of 18 Change is still included with the assumption that the genus’ population from the missing cycle was 0.
