Incidental Dispersal<br />
<strong>The</strong> plant component <strong>of</strong> <strong>the</strong> Taíno diet included wild fruits and vegetables,<br />
such as sweetsop (Annona muricata), macca fat (Acrocomia spinosa) and papaya<br />
(Carica papaya). So far we have focused on deliberate means <strong>of</strong> transforming<br />
<strong>the</strong> natural vegetation; however, in some cases <strong>the</strong> Taínos accidentally encouraged<br />
<strong>the</strong> growth <strong>of</strong> flora not common to <strong>the</strong> specific terrain. Wild plants are<br />
incidentally dispersed in <strong>the</strong> settlement environment by humans and o<strong>the</strong>r<br />
animals and by wind, water and abiotic means. Human incidental dispersal<br />
results from three basic processes: harvesting, adhesion, and mediation<br />
(Rashford 1991, 18).<br />
<strong>The</strong>re are four ways in which incidental dispersal by harvesting can occur:<br />
rejection, loss, discard and defecation (ibid., 18–19). Rejection refers to <strong>the</strong><br />
spreading <strong>of</strong> seeds as a result <strong>of</strong> humans spitting <strong>the</strong>m out. <strong>The</strong> sweetsop<br />
(Annona squamosa) and soursop (Annona sapota) could have been spread this<br />
way. Incidental dispersal by loss occurs when collected fruits are dropped while<br />
being taken from one place to ano<strong>the</strong>r. Discard is <strong>the</strong> intentional throwing<br />
away <strong>of</strong> seeds. Rashford suggests that <strong>the</strong> papaya and mammee (Mammea<br />
americana) were spread via discarded seeds. In <strong>the</strong> fourth method <strong>of</strong> incidental<br />
dispersal, <strong>the</strong> seeds are ingested with <strong>the</strong> rest <strong>of</strong> <strong>the</strong> fruit and later dispersed<br />
through defecation. Guava (Psidium guajava) may have been dispersed this<br />
way.<br />
Rashford (ibid.) points out <strong>the</strong> complexity <strong>of</strong> incidental dispersal, as <strong>the</strong>re<br />
are some plants – for instance, guava – which could have been spread by any<br />
or all <strong>of</strong> <strong>the</strong> methods. In any case, we know that incidental dispersal did take<br />
place: for example, in Jamaica <strong>the</strong>re exists an endemic mountain guava<br />
(Psidium montanum) which is generally found in <strong>the</strong> Lower Montane Mist<br />
Forest between 375 m and 1,200 m above sea level (Adams 1972). <strong>The</strong> location<br />
<strong>of</strong> mountain guava at Taíno sites at lower elevations suggests human incidental<br />
dispersal.<br />
<strong>The</strong> o<strong>the</strong>r methods <strong>of</strong> incidental dispersal are adhesion and mediation.<br />
Adhesion occurs when plants or seeds become attached to people, <strong>the</strong>ir equipment<br />
or <strong>the</strong>ir animals and are thus spread in <strong>the</strong> human environment.<br />
Mediation occurs as a result <strong>of</strong> human settlement, when a built environment,<br />
toge<strong>the</strong>r with <strong>the</strong> activities associated with it, affects animals and o<strong>the</strong>r natural<br />
agents that in turn have an impact on plant dispersal (Rashford 1991, 19).<br />
Generally, it is difficult to prove human incidental dispersal on an archaeological<br />
site. Knowledge <strong>of</strong> <strong>the</strong> processes <strong>of</strong> incidental dispersal, however, can<br />
provide clues to recognizing a Taíno site. For instance, at <strong>the</strong> Meillacan site<br />
at Paradise Park, Westmoreland, <strong>the</strong>re is a very large silk cotton tree (Ceiba<br />
pentandra), 26 m tall. In Jamaica, <strong>the</strong> silk cotton tree is naturally found at ele-<br />
