just a bit bit lah
let them be
at least make make your ladang getah safer
pencuri dont come in and curi you rubber milk coz got people come fishing
maybe wild animals also dont come in coz detect got human present

maybe you makeshift a pondok for them, put rubbish bin and put signboard to be mindful.
maybe they will appreciate you more

that's why symbiosis
probably it help you in some way like i mentioned before
coz just fishing unless they doing drugs there
then different story
