RESULTS ~A~{D COMPARISONS <br /> <br />In 1979,i a inventory was conducted in the City of Ramsey to <br />determine the population characteristics of tree species in the <br />City of ~amsey. (1) In 1992, an inventory was begun to classify <br />~orest Cover types, tree populations, and possible disease <br />problems~ <br /> <br />In !979, .data ~rom 6 sample plots taken in residential areas was <br />eztra ol ~ted to reDresen' bo~h residential (parcels less than Five <br />acres) aod non-residential areas (greater than five acres.) Data <br />~rom thes~ plots may underestimate populations because of physical <br />improvements made to the site. In 1992 data was calculated ~rom 31 <br />sa3nple pl~ts scattered throughout the city. This data assLumed that <br />stands were ~ully stocked· <br /> <br />The results of this inventor%~ will be presented along with those of <br />the !979 program. Because of the difference in the methods of the <br />uwo inventories, analysis of comparisons can be di~icu!t. <br /> <br />Acreage <br /> <br />In ~979,_ 34%~ of Ramsey was considered wooded. Data ~rom the most <br />recent in~ento~y shows that 26% of the city is wooded, a reducsion <br />of 8%. <br /> <br />PoDu!ation <br /> <br />The two re~o~s also depict different po.'puiations. The invento._--y cf <br />!979 was co~nducted almost entirely through aerial photography. This <br />cam emphasize the overstory trees while uending to de-emphasize <br />sma~ ~ a_nd ·~ndersUo_--y trees. =a_s can under es%image %he popuiauion <br />of the lo,est, it should be noted that there was no confidence <br />level esta~iished lot populations in .rural lands (table 3 of 1979 <br />re~oz--L. ) RUral land contained the largest percentage of wooded <br />lands '~ ~ '-~- <br /> · T~s a=~= could be considered ~au!ty. <br /> <br />The populaUion estimates in the !992 invento~ were made ~hrou~h <br />the stanistica! analysis of 30 field Diots.
