Small seed (generally containing rnore than <br /> � 100,U00 seeds per ounce) will be segregated, matched to suitable sites, mixed with sand and haitd <br /> � sprcad to ma�cimize dispersion in their suitable hydrologic habitats. 'I'he upland buffcr areas will <br /> . be drag�.ed atter lhe se�d is broadcast as needed to achieve proper seed to soil contact.
