~~. <br />2 <br />have a far greater survival rats than a seedling. due to i'.s <br />Sncreased ability to store and utilize water, to withstand the <br />drying winds and endure the high evapo-traaspiratiom rate, <br />As far as water requireaents are concerned, xe can expect a <br />096 to 20~ survival rats 18 months after planting seedlings <br />if no irrigation le used, (please refer to the chart on page 20 <br />of the exhibits that xe subaltted at tho- lest lQ,R& -meetiag,_~ <br />If head watering is used tho- percentage of auxviYal would only <br />be slightly increased, according to Itr, Spanlding, because-cost <br />of the water applied to each tree is lost Laediately xith the <br />rapid percolation Sa the planting median, A higkr survival rate <br />ie iaportaat-because the eco-system needs to becoaese-established <br />as soon as possible, The wildlife uses the trees for food and <br />shelter, The tree canopy helps to dissipate the energy of <br />rainfall thereby preventing erosion problems, The root systems <br />help to stabilize the soil. I xotrld like to request that <br />Mr, Spaulding be incited to address these issues at the next <br />nesting of the Board, <br />The east eomaonly used system in this type of revegetstion <br />pro,jeet is the drip irrigation system, If a drip ayaten Ss used <br />xe can expect between 4(>',(r90;6 of the planted seedlings to survive, <br />In terns of cost feasibility, after 2 to 3 years a drip irrigation <br />system is lees expensive than having to replace 90~, of the seedlings <br />every year as would occur without as irrigation system, <br />To simplify the irrigation system, the trees could be ,planted <br />in rows along the length of each beach with spacing betxeea trees <br />to very but still averaging 8' between trees, Itiip Sszigat:Loa <br />technology has advanced significantly in the last fax years a~ <br />many of the early problems, ouch as clogged emitters, can btu <br />totally elialnated, <br />For optimum plant growth topsoil should be brought in <br />from offsite_aad mixed with the stockpiled topsoil. Topsoi'. <br />can be obtained from the construction pro,jecte .where the exisacted <br />limestone is being used la concrete, This iaproved topsoil would <br />result in a far healthier revegetation project, <br />Sincere ,,,/~ <br />c <br />Robert Meldwi <br />
