Well for now you could just do a six way roll table. Small Danger, Small Safe, Medium Danger, Medium Safe, Large Danger, Large Safe. That sort of thing. This is off the top of my head obviously but these islands would have a similar ecosystem wouldn't they? Have one of these for each "biome" [Such as forest/jungle/beach/water] So... I don't know, it would need refining but it may be a good place to start. From there you could expand it to have more flavor variety or more actual rules variety. I'll get back to you on that though.
I actually had a system like that, which requîed two or three rolls per quarry. Really, the current system will be simpler once I finish it.

Send fishers to explore the nearby shores and equip them with shell knives for catching food. Have my gathering children start looking for food in the woods, send the hunters equipped with the remaining shell and obsidian knives and the dog with them for protection and to search ahead of them for evidence of wildlife and a good location to set up camp. If they decide they want to split up, leave one hunter with the kids to guide them home. Order all of the females to wait near where we've made landfall and look for some material with which to construct roofs and seeds to begin farming. Go myself with the stone-working children to gather wood. Let everyone wander for a few hours and then rally them so that we can search for a good place to set up shop, preferably near the shore/relocate to an area one of our parties previously found before.
Amate leads the fishers down the coast. They circumnavigate the island several times, gathering six units of food and three if shell from shellfish. The children and hunters head onto the mountain; the children gather 4 units of roots, while the adults get 10 units of birds, large rodents, and a large spider. They find a few good places for a camp: A bit of flat, coastal rock, a few hundred feet south of the place where the canoe rests and not far from a stream and one of the larger patches of woodland; another point at the summit, where there was a warm depression and a bit of thin soil that could be improved without fear of it washing away; and an islet across a 200-foot-wide, shallow strait towards the south, which has a nearby sandbar that would make a good harbor and a mine of good basalt and obsidian in close proximity. The island is only a thousand feet or so from the little islet to the northern edge, so location isn't as important. Fava Touta and Kaylim Het gather 9 units of wood; the others get 10 of grasses and reeds. The first thing Amate must decide is where to set up camp. Just when he was about to make his decision, Gaula ran down the slope, calling the others. They all ran up, and saw in the crater, hiding behind a boulder, a large lump of reddish, grayish metal.

Have 5 men start a farm. Have 1 man gather wood. Have 4 women gather. Have 2 women construct a shelter.
Wise old Nerjin thinks ahead. He orders five to plow a farm; they finish by day's end. Nerjin heads into the forest, gathering a stick but finding nothing else he can carry. Meanwhile, four of the young ladies gather fruit, or would if they found any which was ripe, edible, and in reach. Doc and Magatha begin work on a hut.

4 competent talented fishermen go fishing with a large canoe
1 male goes and chops wood
the other goes and mines stone
2 women gather reeds/plants/ whatever
2 gather food (getting the pig to aid them)
1 makes a shovel
The other weaves baskets for the gatherers
The children play (or gather water, if needed)
The fishers fish, but the seas do not provide. The woodcutter manages to destroy much of the wood he cuts, bringing back kindling and a stick. The last one takes his pick, and eventually finds a ridge with acceptable mining opportunities. As dusk was approaching, he returned to camp; he came back badly wounded, claiming to have been attacked by a green beast with two clawed feet. The women did not have such an interesting day. The reed-gatherers gather 18 units of grasses and reeds. The food-gatherers gather an excellent 19 units of fruit. The shoveller maker a bunch of gravel, while the basket-maker made a basket. The children play; one gets badlyy injured and one plays Doctor on him.

Damn, dude. No hunting? I had all of my men set to be hunters...I might starve to death!
Two Men will scout as much of the island as they can!
Two Men will enter the Canoe, and go fishing.
Two Men will gather wood with the Adze.
Three Women will gather shellfish and other things on the shores.
Three Women will gather reeds, vines, and other house-making supplies.
The Three children will practice fishing, by hand or with crude rods. The Dogs will go with them, to keep them safe.
((You can hunt, you'll just get more marginal results than other islands. On the bright side, you'll also face less danger.))
Two scout along the isle. One finds a nearby (fairly--only seven miles off) valley, previously hidden by a larger dune, which has a sparse forest. The other confirms the vastness, and notes the presence of straits no more than a couple thousand feet wide or a few feet deep, separating parts of the sandy mass. He also caught a live large crab. The fishers bring in 20 fish! Kamehameha, one of the pair, claims credit. The two sent to get wood search in vain until they are told of the lightly wooded vale, at which point they get five wood. The gatherers bring in three units of edible seaweed and sixteen of seaweed to function as grasses or reeds. The children gladly take the dogs as they practice fishing.

Matta looked around quickly, and decided to give out his orders. First priorities were food and materials.
2 Competant fishers take the canoe and fish along the coastline. If it helps, they take 1 shell knife.
2 Competant heavy labourers take the adze and start chopping wood! The boy helps out.
2 Competant gatherers go with shell knives and gather shellfish at the lagoon.
1 Competant gatherer gathers grass/reeds. The 2 girls help out.
1 stoneworker makes a basalt pick with a chisel and obsidian knife.
The potter collects eggs from the chickens. If it's important, she'll also set up a fire.
The other stoneworker keeps an eye on the kids, giving them additional water if said water is plenty.
2 Competant fighters scout their surroundings, looking for rocks or other materials they could mine safely. Even if the search is reduced, they do not seperate.
((The lagoon has fish and salt.))
The fishers don't find fish, but the wood-getters do wonderfully, gathering 20 wood and 8 G/R with help from each other and the boy. The shellfish gatherers gather 4 units' worth of food and 5 of shell, while the grass/reed gatherers gathered 29 units of grasses and reeds. The stoneworker makes a good basalt pick, seven eggs gathered, and the obsidian knife lost.
What a day.

The hunters will hunt. In a group. With shell knives.
The good stoneworker shall spend his time designing MEGAPROJECT: AQUEDUCT. Children will be employed in finding a (safe) freshwater source, they can do whatever after.
One fisherman shall take the canoe and go seawards. The other will take an adze and produce wood.
Two women will gather reeds. One is to prepare a fire from the reeds and acquired wood, setting one log aside. The last woman shall do general camp preparing duties.
The hunters hunt, but don't bring in any food. The fisher heads, eeny meeny miney northeast, finding a much larger island a couple hundred miles in that direction and noting a few smaller ones. He draws a crude map in the sand when he returns:
The reed-gatherers gather 26 units of grasses and reeds. Half of this and half of the Glorious Settlement's wood are burned in a big bonfire. The children find a spring, then play some. Two would gain skills, but you failed to even inform me of their genders. The woodcutter brings back two sticks, one of which is fed to the fire.
The next morning, the camp wakes to discover rats eating their food! They're shooed away, but only three units of food remain...

Send 4 men hunting with the 3 shell knives, 1 obsidian knife and the 2 dogs. ( Raith, Julius, Maxwell, Seth. )
Send 1 man and 3 women looking for wood or stone deposits with the adze, gather any possible wood. ( Ross, Alexis, Lena, Georgina. )
Send 3 women looking for grass/reeds and points ( Marina, Malissa, Amy. )
Send 1 man and 2 female children to gather shells. ( Alexander, Chrissy, Robyn. )
Send 4 male children fishing on the coast ( Damion, Jack, David, Connor. )
Have 1 female child collect chicken eggs. ( Monika )
Raith leads his party into the hîlls. They return with enough food to feed everyone. Ross brings back a little wood, while the women bring back 15 units of clay to indicate that they lack stone but have clay here. To make pottery, you'll need a furnace, wood, and clay. The other women bring in 19 units of grasses and reeds and 15 basalt rocks, which can be turned into points. The boys fish quite well, catching 20 units of fish! Finally, Alexander returns with the girls and no useable shells. Despite this, everyone has a good day.

Heiruphus and one novice hunter will take knives and hunt [knives]
The navigator and a fisher will go fishing in the canoe
The novice hunter and archer will chop trees [adzes]
The remaining man will take the pick and look for rock deposits [pick]
3 women gather berries
1 woman (medicine) gathers medicinal herbs
2 women gather grasses/reeds
1 woman collects water if needed, gather shells if not.
3 children play.
Heiruphus and the other get two units of food. The fishers damage the canoe and catch no fish. The woodcutters also fail to cut wood usefully. The rock-searcher mines five obsidian rocks from a random cliff. The gatherers gather 3 units of medicinal herbs and 21 units of grasses and reeds. The children play. They claim that neither the loss of the chisel and a knife nor the injuries sustained by the boy had anything to do with them. They do, however, offer a crude shovel as penance.

That evening, everyone sees a plume of smoke from the ocean. Except Maya and his Glorious Settlement, of course.

That seems to be everyone.
