1	Small Plantations	plantations_01	Despite the lack of water, these small plantations succeed in growing particularly hardy fruit.
2	Trading Posts	plantations_02	Hardy desert nomads travel between trading posts, bringing food with them to wherever it is needed the most.
3	Weavers	plantations_03	Weavers spin cloth in their workshops, which they then trade to the desert nomads.
4	Wellsprings	plantations_04	With limited water, a new well is sure to make the area prosper. Several such springs have been discovered, and proper wells have been constructed.
5	Caravanserais	plantations_05	Larger trade caravans need a place to stay so that their animals can rest. The caravanserai provides the space they need and is also an excellent place to tax their goods.
6	Date Groves	plantations_06	With more land being suitable for plantations, date groves are being cultivated. The sweet dates last for a long time, and are a valuable good for traders.
7	Irrigation	plantations_07	By flooding fields with water from the wells, they can support something more than pure subsistence farming. This is a large task however, making the desert bloom is not easy.
8	Large Plantations	plantations_08	These plantations now produce a definite surplus, which can be traded and sold for a profit.

Level	Name	Internal ID	Description
1	Crop Fields	cereal_fields_01	Crop fields, the backbone of the feudal economy, each manned by a small but generous family of peasants – all but willing to surrender most of what they produce in tithe to the crown!
2	Hamlets	cereal_fields_02	The construction of more hamlets means that more peasants can be put to work in the fields. And as we all know, more peasants mean more taxes!
3	Barns & Storehouses	cereal_fields_03	The erection of barns and larger storehouses allows peasants to preserve hay and straw, gives them a place to store their tools, and acts as an impromptu place to house traveling armies (or vagabonds...).
4	Farmsteads	cereal_fields_04	Larger farmsteads support larger peasant families. When families have space to grow, they will produce children that can be put to toil in the fields – as is the natural order of things!
5	Granaries	cereal_fields_05	Granaries allow farmers to store grain, vegetables, and fruit for long periods. Of course, the farmers are happy to give it all up for our soldiers, should they happen to march on through!
6	Granges & Tithe Barns	cereal_fields_06	Tithe barns act as a place for farmers to put the portion of their produce that should befall the clergy – of course, this also makes it easier for us to tax them.
7	Vast Crop Fields	cereal_fields_07	By 'encouraging' our grateful peasant subjects to till more and larger fields closer to each other's lands, we are sure to get a higher yield. Of course, this encroaching on each other's lands might bring conflict between the farmers – alas, it is a sacrifice we are willing to make!
8	Grain Silos	cereal_fields_08	These massive silos aim to store grain in vast quantities throughout the entire year. There's so much that no single army can consume it all, of course, that is presuming that no rats enter the silos...

1	Logging Camps	logging_camps_01	Woodcutters have set up camp along the outskirts of the forest, working long days with cutting down trees.
2	Resin Collectors	logging_camps_02	All along the forest resin is being collected for use as an adhesive, or to be sold to the clergy for use in various rites.
3	Charcoal Burners	logging_camps_03	The charcoal burners work tirelessly through smoke and smog to produce the valuable material that is so sought after by blacksmiths.
4	Wood Pastures	logging_camps_04	Among the trees pastures can be found, with the animals feeding on the naturally occurring seeds and nuts. For a few months in particular each year, a glut of nuts fatten the animals up for the winter.
5	Tilled Fields	logging_camps_05	Where trees once stood, fields now lie. Former forest makes for formidable farmland.
6	Honey Pastures	logging_camps_06	On the edge of the forest, apiaries are placed to capitalize on the now-abundant amount of wildflowers that have appeared where the forest once stood.
7	Forest Glassworks	logging_camps_07	The forest makes the perfect place for the glassblower to work. With easy access to most materials they need, valuable glass can be produced and traded with.
8	Sawmills	logging_camps_08	While axes and simple saws have served us so far, the sawmill is to those like god is to men. Now the forest can be consumed in almost no time, with its valuable wood fueling our cities and towns.

1	Hillside Fields	hill_farms_01	Along the sides of the many hills there are numerous small fields, growing crops and sustaining a small peasant population.
2	Fell Pastures	hill_farms_02	Cattle is brought to the uncultivated uplands, or fells, and allowed to graze on the plentiful grasses that grow there.
3	Root Cellars	hill_farms_03	Root cellars allow for year-round storage of vegetables, something that is of dire importance in the sparsely-fertile hills.
4	Vegetable Fields	hill_farms_04	Large fields of vegetables provide the sparse farms with much-needed food.
5	Lynchets	hill_farms_05	By diverting water from a nearby stream into a terrace, the hillside fields can be kept fertile for longer.
6	Roads & Stairs	hill_farms_06	By connecting the spread-out farms and hamlets with proper roads and stairs, we increase our efficiency at taxing them.
7	Winter Granaries	hill_farms_07	During the harsher months of the year, there's not much for animals to eat, something which the winter granary solves.
8	Apple Orchards	hill_farms_08	The rolling hills provide the perfect environment for orchards, particularly of the apple variety.

7	Consolidated Landholdings	farm_estates_07	Several different manors, all run as one — by letting the most productive families take the reins from the less productive ones, we guarantee excellent results.
