Stocks’ Saltwort (Lana)

Stocks’ saltwort (Haloxylon stocksii, locally lana, and now placed by botanists under the accepted name Soda stocksii) is a leafless succulent shrub for the ground most farm plants refuse — the salt-crusted sandy flats of the Sindh coast, the saline patches of the Punjab plains, and the dry valleys of the Balochistan highlands.¹ Where a field has gone white with salt and grasses have given up, this is one of the few shrubs that will hold the soil, feed a camel, and give you firewood off otherwise dead ground.

Where it thrives

This is a true halophyte, a salt-lover rather than a salt-tolerator. It flourishes in salt deserts where soil salinity runs between 19 and 34 dS/m, levels that would kill almost any crop, and it copes by taking salt up into its stems and diluting it through extra succulence.² POWO records it across eastern Afghanistan, Pakistan, and north-western India in desert and dry-shrubland country.¹ It asks for full sun and free-draining sandy or sandy-loam ground, and it shrugs off the drought and heat of the lower Indus basin. What it needs is salt and space, not fertility.

Role in the system

On saline land Stocks’ saltwort is a support and reclamation species, not a centrepiece. Because it includes salt in its tissue, it slowly draws salts up out of the root zone, and stands of it stabilise loose, salt-affected sand that would otherwise drift.² Planted in a belt it breaks the wind across an open flat, and the cover it throws lets less salt-hardy plants establish in its lee. It fixes no nitrogen, so pair it with a legume once the worst of the salt is buffered. Think of it as the first tenant that makes the address liveable for everything that follows.

Grazing value

The succulent shoots are browsed by camels, sheep, and goats, and the shrub has been studied as a cattle feed under saline conditions, which is rare and valuable on land that grows little else.³ The catch is honest: like most chenopod browse it is high in salt and ash, so it works as a component of the diet, not the whole of it. Animals need fresh water alongside it and a complementary feed to balance the mineral load. Used that way it turns a salt flat into dry-season browse.

Establishment

Collect ripe seed from established Sindh or Balochistan stands in late autumn, and sow it fresh, because viability falls off quickly in storage.² On bare, salt-crusted flats direct seeding is often unreliable, so the surer route is to raise seedlings in a nursery and transplant them out. Give it full sun and free-draining sandy ground; it needs no fertiliser and no fresh-water irrigation beyond getting young plants started. Spaced through a salt-affected patch it gradually closes into a stand that holds the soil.

Cautions

The salt and ash content that lets it survive also limits how much stock should eat at once. Like most chenopod browse it is high in salt, so offer it as one component among other feed rather than as a sole ration, and keep drinking water close at hand for the animals on it. On non-saline ground it has no real advantage over easier, more productive shrubs, so do not waste good soil on it — reserve it for the salt-affected patches and white flats where almost nothing else will grow and it genuinely earns its place.
