What do they look like?

• In deep water they move very fast but may only be 0.5 to 1m high • In shallow water they slow down and become higher

(Source: National Oceanic and Atmospheric Administration, NOAA) A comparison with wind waves at the coast

• Tsunamis are often the same height as wind- waves • It is the volume of water behind them that causes the damage

Wind-wave Tsunami Wave period 5 to 15 sec 20 min to several hours Wave length 100 to 200 m 200 to 350 km Wave height 20 to 50 cm 20 to 400 cm

DENR National Greening Program: 1.5 B trees/1.5 M ha/ 6 yrs: 10% indigenous species + 50% fast-growing species (exotics e.g. Swietenia mahogani) & trees • exotics suitable for commercial plantations - not biodiversity conservation, watersheds & Climate Change mitigation • plant native flora – but which species? • beach forest spp. – coIonizers that thrive in full sunlight, inadequate water, poor nutrients, therefore ideal for NGP; from beach to 200 km inIand, 200 masI • many refo areas bare sites (= beginning), so pIant colonizers, eg, coastal talisay, botong, bani vs climax flora (= at the end, eg, dipterocarps take 17-30 years to fIower) LET’s USE BEACH FOREST TREES FOR NGP REFO!!
