(Maxwell,  2015). The  long  and  impressive  history  of  sustained  use  and  management  of  Malaysia’s  Matang  mangroves  has  provided  a  foundation  for  confidence  in  mangrove  restoration,  management  and  wise  use  (conservation).  Chan (2014)  discussed  the  successional  dynamics  of  this  Avicennia-Sonneratia  forest  merging  with  an  ecotone  of  Rhizorphora-Bruguiera  forest.  Geomorphology  (a  physical  process),  mud  lobster  (Thalassina  anomala)  activity  (a  biological  process)  (Havanond,  2000)  and  forestry  (anthropogenic  activity)  have  all  combined  to  help  sustain  a  successful mangrove  ecosystem.  Here  overt  mangrove  biodiversity may  be  poor but  the  hidden  subtle  biodiversities  invite  more  attention. Importantly,  the  long  term  success  of  Malaysia’s  mangrove  forestry  when  combined  with  decades  of  mangrove  eco-repair  and  conservation  in  Thailand  by  Akornkoae,  Havanond  &  Paphavasit  and  their  teams  have  shown  t h a t   l i m i t e d - s p e c i e s   mangrove  plantations  are  both  sustainable  and  eco- economically  multifunctional  (e.g.  Aksornkoae  et.  al.,  1993;  Aksornkoae  et.  al.,  1996;  Havanond,  2000;  Paphavasit,  1995;  Paphavasit  et.  al.,  2004). However,  the  many  eco-restoration  opportunities  on  offer  invite  us  to  include more sub-dominant  species  which  display  properties  such  as  anti-fouling  (anti-barnacle)  e.g.  Ceriops tangel  (Chan  et.  al.,  2015;  Chen  et.  al.,  2008)  and  Kandelia  candel  (Maxwell  &  Li,  2006)  and  emerging  bio-medical  features  as  in  the  case  of  Bruguiera  gymnorrhiza  and  Xylocarpus granatum. 3.3  Is  Avicennia  marina  our  “A  class”  candidate  mangrove  in  an  unstable  climate? A .   m a r i n a   i s   o n e   o f   e i g h t  Avicennia  spp  globally  (Spalding  et.  al,  2010)  with  this  remarkable  species  showing  the  greatest  range  of  eco-physiological  tolerance  and  adaptations  to  temperature  (hot  and  cold)  tidal  inundation,  rainfall,  salinity,  anoxia  and  substratum  type  (Aksornkoae  et.  al.,  1993;  Saenger,  2002;  Maxwell,  2015).  A.  marina  also  offers  hope  in  terms  of  this  species  placing  a  clearly  visible  utility  on  mangrove  vegetation:  it  has  multiple  eco-economic  values.  These  include  its  role  in  human  food  (Hong &  San,  1993);  high  protein quality  fodder  for  milk-producing  cattle  at  Gujart,  India  (Baba  et.  al.,  2013)  and  on  New  Zealand  dairy  farms  (Maxwell  &  Lai,  2012);  as  estuarine  river  stop-bank,  sea-dyke  storm  and  tsunami  protectors  (Maxwell,  1976;  Hong  &  San,  1993;  Aksornkoae,  2004  and  Havanond,  2005)  and  perhaps  most  attractive  of  all,  as  a  source  of  bioactive  cytotoxic  compounds  to  contain  human  leukemia  and  breast  cancer  cells  (Baba  et.  al.,  2016)  together  with  a  mosquito  larvacide  property  associated  with  tannin- polyphenols  exuded  mangrove  material  acting  as  a  mosquito  repellent  (Primavera  et.  al.,  2004).  The  recent  discovery  of  the  Rhizophora  (R.a  x  R.m)  hybrid  reported  above  and  the  displays  of  ecotypicity  by  Avicennia  marina  and  Kandelia  candel  (Maxwell,  2007)  also  serves  to  remind  us  that  biodiversity  is  dynamic  and  even  in  our  short  time  spans  is  part  of  a  big,  holistic  picture  of  pragmatic  approaches  to  biodiversity  in  today’s  world. IV.  CONCLUDING  THOUGHTS:  TIGERS  AND  BIG MANGROVE  ECOSYSTEMS 4.1 With  almost  140,000  ha,  we  could  easily  contend  that  The  Sundarbans  of  Bangladesh  is  the  world’s  greatest  and  most  important  biodiversity  bank  for  the  mangrove  ecosystem.  In  December  2014  an  oil  tanker  carrying  some  358,000  L  of  furnace  oil  capsized  in  Sela  River  near  its  confluence  with the  larger  Pasur  in  Chandpai.  The  ecological  impact  of  this  disaster  is  not  yet.  fully  known  but  will  need  to  be  approached  at  an  ecosystem  74 Proceedings  of  the  International  Conference  on  Climate  Change,  Biodiversity  and  Ecosystem  Services  for  the Sustainable  Development  Goals  (SDGs):  Policy  and  Practice  27-29  June  2016,  Cha-am,  Phetchaburi,  Thailand
